Hi,

I’m planning a trip to Indonesia, specifically Sulawesi and Java, in September for 10 days. I don’t know this part of the world at all—any advice is welcome! I’ll be traveling solo and would also love tips on meeting other travelers or locals.

Thanks

Hi there, As we’re putting the finishing touches on our travel journal, we could really use your help, please. We’re heading to Thailand in three weeks and will be in Chiang Rai right during the burning season... Will the stunning road between Chiang Rai and Pai still be beautiful? Are the landscapes green like we’d expect at this time of year, or are they dry with gray and brown mountains due to the drought? We were planning to rent a car, but that’s a lot of time we could spend elsewhere if it’s not worth it! Thanks for your help.

Hi, just a quick note mainly for Samsong, even if he’s still giving me the silent treatment. I’ve been in Nan since yesterday and... I love it! So thanks, Thierry. It’s exactly the kind of place I’d been dreaming of... Even if communication is a bit tough, it’s not impossible. They don’t even know the most basic English words! Everyone laughs and they’re the first to pull out their phones to... translate. They’re even quicker on the uptake than I am. And then there’s the time I say Nan (pronounced "Nane"). They don’t understand me. After a while (sometimes a long one), they reply: "Ah, Nan?" (pronounced "Nane") 😵🤳😃

The town is exactly how you described it back in 2022. Though I’m surprised to find so many trendy, slightly intellectual "Cafés." Apparently, coffee—excellent everywhere—is king in Nan. It feels like a university town. And it seems pretty lively at night! But for now, I’m going to bed early. I caught a nasty cold, which didn’t stop me from walking 12 km this morning. But I came back to my accommodation by 3 PM (gorgeous and luxurious with top-notch service for 800 baht—even a cute local welcome gift this morning, plus other unexpected touches like a bottle of honey and chrysanthemum flowers for tea. The lady must’ve guessed I was coming down with something yesterday). I thought about going out for dinner but didn’t have the energy. I think I’ve got at least 39°C fever...

Anyway, I’m sending you this message, Thierry, because you mentioned a daily bus to Chiang Rai, so I didn’t look into it. But now it’s a real problem—no buses to Chiang Rai, only taxis. At least 2,500 baht for the cheapest one! I’ll check the bus station directly tomorrow. Online, it’s all taxis, no buses. I’d like to explore the countryside/mountains if I can find an affordable driver. Any ideas for destinations or itineraries? Thanks.

Hi there, Yesterday in the Thailand section, 100% of the new threads were just about beach destinations 😕... So here’s the counterattack in the form of this photo thread, dedicated solely to the countryside: the locals, their livestock, fields, farms, rice paddies, small rivers, and agricultural machinery. If you’ve got any pictures that fit these categories, feel free to add them! Comments welcome. For each photo, I’ll (or you can) indicate the area where it was taken.

Hi there, we’re landing at Hanoi Airport and would like to head straight to Cao Bang without going into Hanoi. Does anyone know if there are buses that go directly from the airport to Cao Bang (especially in the early afternoon)? Thanks in advance!

hi everyone, I want to travel in the north for 3 weeks in September-October 2026 to meet ethnic minorities, photograph mountain rice terraces and their harvest, and revisit Halong Bay—but maybe Lan Ha Bay instead. Can you recommend one or more local agencies? Thanks, and happy holidays!

Hi there,

We’re planning a 17-day trip to Indonesia starting on April 22nd and would love to hear your suggestions. We’re looking for itinerary ideas or places to see monkeys, birds, and beautiful rice terraces, as well as interesting natural spots like lakes or waterfalls. We’d also like to avoid overly long distances and limit ourselves to a maximum of one internal flight. For the last three days, we’d love to end the trip on a stunning beach with the chance to swim with manta rays. If you have any recommendations, must-see spots, or experiences not to miss, we’d be thrilled to hear them. Thanks in advance for your help! 😊

Hi there, We’re planning a 3-week family trip next summer with our three kids, who’ll be 8, 8, and 7 years old.

After some research, we’re leaning toward Malaysia to combine nature/forests and paradise beaches. The idea is to introduce our kids to the country’s culture, nature, and wildlife.

We want a great trip but without splurging on luxury options like high-end lodges and resorts. We’re looking for comfort with a touch of authenticity—basically, a good middle ground.

I’ve started putting together an itinerary and would love your expert advice and tips to help us build this amazing trip with our little ones.

Day 1: Departure from France

Day 2: Kuala Lumpur Stay at a hotel near the airport or KL Sentral. Just one night.

Day 3: Morning flight to Sandakan (Borneo). Stay in Sepilok

Day 4: Sepilok: * Orangutan Center * Malayan Sun Bear Center * Rainforest Discovery Centre

Day 5: Depart for Kinabatangan. Boat safari in the late afternoon.

Day 6: Sunrise safari. Jungle walk. Evening safari.

Day 7: Final safari. Return to Sandakan.

Flight to Kuala Lumpur, then to Kota Bharu (or overnight transit depending on schedules).

Day 8: Transfer to the port. Boat to the Perhentian Islands.

Days 9 to 13: Perhentian Besar 5 full days. * Snorkeling * Hiking * Turtle watching * Wild beaches * Relaxation

Day 14: Return to the mainland. Bus or private car to Taman Negara.

Days 15 and 16: Taman Negara.

Day 17: Return to Kuala Lumpur.

Day 18: Visit the Petronas Towers or Batu Caves

Day 19: Free day.

Day 20: Return flight.

Thanks in advance, everyone!

Hi there, I can’t seem to find a car rental with a driver for several days in Chiang Mai to explore the surrounding areas, preferably in the countryside/mountains, villages, etc. Would anyone have a driver to recommend? Thanks

Hi there, fellow travelers,

My mom and I are heading to Indonesia on July 11, 2025, for a month. We’ll spend 15 days in Borneo (Kalimantan) and 15 days in Sulawesi. We’re traveling with backpacks and really want to meet locals and experience their culture. We have a layover in Singapore before flying to Borneo, but we’re not sure yet which part of the island we’d like to land in.

I’m looking for the most up-to-date info possible because our research results are pretty confusing. Initially, we wanted to focus on the Indonesian side of the island, but we’re finding way more info on the Malaysian side (better tourist infrastructure). We’re feeling a bit lost...

Our priority is a 4-5 day trek max. We also want to connect with an English-speaking guide to explore Borneo’s primary forest and its wildlife. Ideally, we’d like to venture into the island’s center. But we might not have the time (given the lack of infrastructure and long distances—we don’t have 15 days just for a trek) or the physical stamina to get there. Still, we’d love to get off the beaten path and avoid pricey, touristy excursions. From our research, we’ve come across 3-day, 2-night trips on longboats or 4x4s (e.g., orangutans in Tanjung Puting) for 400 to 500 €. But that’s way out of our budget, and we think it’s too expensive. We get that as tourists with higher incomes than locals, we should pay more—but there’s a limit, especially compared to the cost of living in Indonesia. We want to avoid tour operators and crowds of tourists. Our goal is to see what’s left of Borneo’s preserved and wild tropical forest and observe animals in their natural habitat. If we don’t see any during a trek, oh well—we’ll take our chances.

On the Malaysian side, there’s Danum Valley, and on the Indonesian side, places like Gunung Palung, Betung Kerihun, and Kayan Mentarang...

What do you think?

Does anyone have any tips?

Has anyone here met indigenous communities on the island?

Does anyone know a friendly local guide?

We’d love any extra info on Borneo and Sulawesi! ;)

Take care!

Hi there,

I’m planning a trip to Cambodia and was set on visiting the Ratanakiri region, which seemed to match what we love most in terms of landscapes: forests, jungle, greenery...

However, as I started looking into the area, I read that deforestation there is massive, and some of the info on the topic is years old—the situation hasn’t improved since, unfortunately.

So my question is: is Ratanakiri still worth visiting, and does it justify the long travel time and distance to get there?

I’ve seen that jungle treks are possible, but from experience, I know guides sometimes hesitate to venture deep into the forest and stick to shorter walks along the edges of parks.

Thanks in advance for your feedback.

Hi there, I’m so glad the VoyageForum is back up. Reading 'Montagnard74’s' Laos trip report (which I read yesterday) made me want to share my own (which I already posted a year ago on another forum). Here’s a little recap of our 3 weeks in northern Laos, plus a few days in Vientiane. By the way, we could easily go back to the north—there’s so much to see and do; probably in a few years.

This was our 3rd trip to Laos after having already done:

1st trip in 2012 (3 weeks), a quick overview: Vientiane Vang Vieng Luang Prabang Plain of Jars

2nd trip in 2017 (1 month): Vientiane all the way to the 4,000 Islands via Thakhek, Kong Lor, the Bolaven Plateau, Savannakhet, Pakse...

Our 2023 itinerary (1 month): Vientiane Luang Prabang Muang Ngoi Nong Khiew Luang Namtha Muang Sing Boten Vang Vieng Vientiane

Some general info (2023): For those who’ve already been to Laos: everything has gone up a lot—I think prices have almost doubled for transport, accommodation, meals... everything. But Laos is still a budget-friendly country for us. As a couple, we spent 1,100 € for a month, all included (and we definitely didn’t skimp on massages :)).

Don’t trust the transport signs posted everywhere—at travel agencies, bus terminals, hotels... THEY’RE ALL WRONG (especially the schedules). They haven’t been updated since before Covid.

There are hardly any bikes for rent anymore, but scooters are easy to find everywhere. We switched our mode of transport toward the end of our stay: from bikes to scooters, which let us go farther. In Vientiane, we only saw one bike rental place, near Ong Teu Pagoda.

BCEL bank doesn’t charge a commission on foreign currency exchanges. Using ATMs is expensive due to fees. Outside Laos, Lao kip are basically worthless. There’s so much inflation that I couldn’t find a single bank or exchange office willing to swap the kip we had left. So, don’t exchange too much toward the end of your trip.

Some little tips from our experience (2023): The Muang Koua to Muang Ngoi boat still runs daily. At the dam, you have to get off and take a bus, then get back on the boat.

The boat from Muang Ngoi to Nong Khiew only leaves at 9:30 AM (don’t miss it or you’ll pay a lot for a private boat). From Nong Khiew to Muang Ngoi, there are at least two boats a day.

From Luang Namtha to Muang Sing: 4 to 5 buses a day, the last one leaves around 3:30 PM.

From Luang Namtha or Muang Sing to Nateuy or Boten (to catch the new train): 3 to 5 buses a day.

The new train is really hard to book—it’s often fully booked 48 hours in advance, even the local train (5 hours from Boten to Vientiane instead of 3 hours on the high-speed train). (That makes it tough to travel day by day, which we love... too bad.) For baggage checks: don’t bring anything flammable (sprays...) or sharp. My mosquito repellent (flammable but in a small plastic bottle) got through. Water bottles and a tiny pocketknife are okay. But it seems to depend on the station.

Some guesthouses prefer to be paid in dollars, otherwise the price is much higher.

If you’re entering Laos from Vietnam via Dien Bien Phu, you have to get your visa at the embassy in Hanoi—otherwise, you’ll be refused at the border (no e-visa or visa on arrival).

Apart from Luang Prabang, Vientiane, and Muang Ngoi/Nong Khiew, there are very few tourists.

Some bus prices (in addition to those mentioned in my trip report) (with pick-up) 2023: Luang Prabang to Luang Namtha: 320,000 kip per person, 9h LP to Phonesavan: 250,000 kip per person, 7h LP to Phongsaly: 450,000 kip per person, 13h LP to Huay Xai: 420,000 kip per person, 14h Train Nateuy to Vientiane: 400,000 kip per person LP to Chiang Rai: 780,000 kip per person, 18h LP to Hanoi: 900,000 kip per person, 24h LP to train station: 50,000 kip per person LP to airport: 100,000 kip per person Vientiane from train station: 180,000 kip by taxi

Boats: LP to Pak Beng: 300,000 kip per person, 1 day LP to Houay Xai: 500,000 kip per person, 2 days LP to Pak Ou: 180,000 kip per person, 5h

Hi there, After visiting southern Sumatra in 2020 (Padang area, Bukkitinggi, Lake Maninjau), we’re heading north in two weeks to explore. We’ll arrive in Medan after Singapore. Then we plan to go to Bukit Lawang, Berastagi, and Lake Toba before finishing up on Pulau Weh. Yeah, I know three weeks is short, but we like taking our time now that we’re in our fifties 😄. My questions: - Which direction should we do the loop: Medan → Bukit Lawang → Lake Toba → Medan (we’ll be traveling by taxi)? - Can I buy the Medan/Banda Aceh flights just 10 days in advance while we’re there? Any airline to prefer? Thanks in advance to anyone familiar with this part of the world 😊

Hi there, we’re currently in Mai Chau and tomorrow we’re hitting the road back to Hanoi to head up toward Bac Ha and Sapa. We haven’t really had a set plan since we arrived—we’ve already done the Halong Bay on land and by sea. I’ve got 2 free days before heading to Bac Ha and Sapa. Any tips? Thanks, and looking forward to hearing from you.

I really loved Thailand, but it was too touristy for my taste. So I'm hesitating about going back and wondering if Cambodia or Vietnam would be less crowded with tourists...

Hi there,

I’m heading back to Thailand soon, and from what I’ve been reading, it seems some beaches/islands are infested with these dreaded sandflies!

I’ve noted the remedy: rub the bitten area with 90% alcohol, then apply soothing cream.

But prevention is better than cure!

Which areas should I avoid right now?

Are there seasons that are more prone to these itchy invasions than others?

I’ve already stayed in Hua Hin, Koh Samui, Koh Phangan, Koh Tao, Krabi, and Phuket without any issues like this.

I’d love to keep it that way...

Thanks

Hey everyone, I travel quite a bit, and I’m here to share my thoughts about an upcoming trip to Indonesia, specifically the Togian Islands.

I’m planning to go for 3 or 4 weeks in July-August and looking for a sunny destination that’s not too expensive (flights + cost of living), with varied points of interest. About fifteen years ago, I had planned a trip to the Togian Islands, but it didn’t happen, so I’m revisiting this destination (Sulawesi, Toraja country) + maybe others? Given that in Indonesia, I’ve already done volcanoes in Java, Bali, part of Lombok, and the Gili Islands. The issue is that I’ve read some posts about the plastic waste problems around the Togians, and it seems like they’re not the paradise islands they once were.

So, I have a few questions: I’d love to hear recent feedback from travelers who’ve been to the Togians to get an objective opinion (?) or if you’d recommend other paradise-like islands in Indonesia (not overcrowded).

If you confirm that it’s still an exceptional destination, what did you pair it with? The Moluccas and which islands in particular? Or Flores/Komodo? For my part, I don’t scuba dive—just snorkeling.

Finally, if you have other dream-island destinations (affordable and sunny), I’m all ears.

Thanks in advance!

Good evening,

Our family trip (2 kids, boys aged 6 and 9) is coming up fast, and I have a few questions. I’ve seen that quite a few people on this forum are active about Thailand, so I hope you can help me out :-)

- I have a Free mobile plan with a good amount of data abroad (35GB). Do you know if the Bolt or Grab apps work well with a French SIM? I’ve read that the app might not work if the SIM isn’t Thai, but I’ve also seen French travelers using their SIMs in Thailand, so I’m not sure what to think.

- What tips do you have to avoid traveler’s diarrhea (especially for our 6- and 9-year-olds)? I’m already preparing them to wash their hands often and not put their hands in their mouths or brush their teeth with tap water (they’re still little and might not control the water well in their mouths). Are there certain dishes or food stands to avoid? Are ice cubes really off-limits too?

- We arrive in Bangkok at 9 AM, and we have a French-speaking guided tour scheduled for the next morning (all day). The itinerary isn’t finalized yet with the guide—I need to get back in touch soon. What do you recommend doing on that first day, which might be tiring after the long flight and jet lag? Our hotel has a nice pool, but I’d love for us to get out and explore a bit :-)

- Is the Grand Palace really best visited early in the morning to avoid crowds?

- I’d love to visit a night or floating market, but they’re all on weekends. Unfortunately, we’re in Bangkok from Wednesday to Saturday morning (then we take the train to Ayutthaya in the morning). Is there a market on Friday night? I saw Chatuchak, but Friday night doesn’t seem like the best time—is it still worth going?

I’ve looked for answers to these questions, but I’m either not finding a definitive answer or I’m overwhelmed by all the things to do/see in Bangkok. So, I’m hoping your advice or experiences can help me out!

Thanks in advance, and have a great evening! :-)

Hi there, I’m planning my trip to Flores, Indonesia with a 6-year-old child. I’ve contacted driver-guides who are quoting astronomical prices for one week. Is a guide really necessary? Or would a driver who knows the area well be okay? Do you think I should book from France, or wait and arrange it day by day once I’m there? What’s the average price?

Also, do you think the daily drives won’t be too long?

Thanks

Hello, We’re a family of four with two teens aged 16 and 18. We’re heading to Thailand this summer. We’ll arrive in Bangkok and plan to take a flight to Luang Prabang. I’ve seen there are some great visits and excursions to do (temples, markets, waterfalls) and maybe even venture a bit north to places like Nong Khiaw, Muang Xay, Muang Ngoy, or Oudom Xay. But I’ve also heard about the Bokeo region with the Gibbon Experience. Since we won’t be able to do everything, I’d love to hear about your experiences, impressions, and advice on the two options I’m considering, especially since we’ll be meeting family in Chiang Mai, Thailand, afterward.

Option 1: A loop from Luang Prabang heading slightly north, then a flight from Luang Prabang to Chiang Mai.

Option 2: A few days in Luang Prabang, exploring within a few dozen kilometers around, then heading to Bokeo province for the 2-day/1-night Gibbon Experience. For this option, I saw on Rome2Rio that it’s possible to book a ferry trip on the Mekong from Luang Prabang to Huay Xay—they mention about 8 hours. But is that realistic? What type of boat is it? Then, to get to Chiang Mai, there aren’t many options—bus or minivan—but how does crossing the border work?

Finally, for those of you who’ve been to Laos in August, what was the weather like? We’ve already visited Thailand, Vietnam, and Cambodia during the same period over the past four years and weren’t really bothered by bad weather.

Thanks for your feedback! Best regards, Aurélien

Good evening, I’m posting a new message after browsing the forum. Our 16-day backpacking trip (late June to mid-July 2026) focused on hiking and connecting with locals is starting to take shape, but I’d love your input. I’m torn between two routes: Option 1: A loop from Hanoi to Hanoi, starting with Bai Tu Long Bay, then Tam Coc, Mai Chau, Pu Luong, Mu Cang Chai, and the area around Sapa, before taking the train back to Hanoi. Option 2: The same loop but starting in Sapa and ending in Bai Tu Long Bay. What do you think? Thanks in advance for your help—I’m looking forward to reading your thoughts. Cédric

Hi there! We’ll be in Bali from July 28, 2025, to August 28, 2025, and we’d love to know which spots are worth visiting. If anyone has a travel journal or tips to share—especially since we’ll be spending our first week in Uluwatu—thanks in advance for your replies!

Hello! So glad to see the forum back up and running! We just got back from a trip to Sumba in early November—spent a little over a week exploring this lesser-known island from east to west. It’s the perfect destination for anyone looking to escape overtourism. Feel free to ask any questions—everything’s still fresh in my mind, so I’d be happy to help if I can.

My itinerary: - Arrival in Tambolaka - The lagoon, beaches, villages, and stunning waterfalls…

Happy to share more! Check out my photos on my Flickr

Hi everyone, so glad the forum’s back up! I’m planning a trip for next June but I’m still torn between Papua and Papua New Guinea. Solo backpacking trip, about 3 weeks (trekking, culture, and a tiny bit of beach time). It’s still tough to find recent info—anyone know if backpacking is doable there? Thanks in advance for your tips! carpediem

Hi everyone, I’m currently planning a trip to Malaysia for January 2025. I’ve got three transport questions for you all!

1: I arrive at 3 PM at Kuala Lumpur Airport and plan to take a direct bus to Malacca. Is booking a bus for 5 PM feasible, or is it too tight after collecting luggage? And which platform is the most reliable? Redbus, 12GO Asia, Rome2RIO, busonlineticket? Or can I buy a ticket on the spot without a reservation? Is that too risky? Alternatively, is it better to take a Grab? I saw the fare was around 60 €. Can you confirm this price? And is it easy to find a Grab from the airport for this distance?

2: Penang to Cameron Highlands (Tanah Rata) route—I saw there’s a direct bus that takes 5 hours. Can you confirm this? And is this duration realistic?

3: Cameron Highlands to Pangkor: This one’s tricky... The best I’ve found is 2 buses + a ferry + a taxi. Do you have a better suggestion?

Thanks for your help! Guy

Hi there, I’ve found so many tips and reviews on this forum, so it’s my turn to contribute a little. We spent just over two weeks with our family, with the following itinerary: - Hanoi: 5 days - Halong Bay: 3 days and 2 nights - Tam Coc: 3 days - Mai Chau: 2 days - Sapa: 3 days We got around by bike, scooter, Grab, and bus. Our main accommodations were homestays and hotels in Hanoi. We visited lots of museums, temples, and neighborhoods in Hanoi. We did a 2-day, 1-night trek in Sapa with May, a Hmong local, without going through an agency. A few small regrets: the weather was overcast, and we couldn’t make it to Fansipan, but nothing major 😅. We also couldn’t find transport to get from Sapa to Mu Cang Chai. Other than that, this trip will stay in our memories for the kindness of the Vietnamese people, the connections we made, the food (street food, homestays...), the coffee 😋, the landscapes, and how easy it was to get around... Our goal was to take our time and focus only on a small part of northern Vietnam. If you need any tips or recommendations, don’t hesitate to ask. Looking forward to hearing from you. Cédric.

Hi everyone, My 16-year-old son, my partner, and I are planning a trip to Malaysia in August.

Here’s what I’m thinking so far:

- KL (4 nights): The first day is a write-off, so that leaves 3 full days. - Cameron Highlands (2 nights): 1 full day for Mossy Forest, etc.

Now, the big question. I’m planning to go to Penang—either 3 or 4 nights. If I do 4 nights, I’ll have 3 full days to explore. If I do 3 nights, I’m thinking of spending 1 night in Ipoh.

Is Ipoh worth it for a day? Is 3 full days in Penang too much? - Perhentians (4 nights).

To finish, back to KL and a visit to Malacca, or maybe Singapore—but if it’s just for a day, it might not be worth it.

Thanks in advance for your feedback!

Hello everyone, we’re planning a trip to Vietnam at the end of June 2026 for at least two weeks. Our goal is to avoid rushing around too much and take our time, focusing on nature, hiking, and getting to know the locals. Here’s my first draft itinerary: Arrival and departure from Hanoi Sapa and its surrounding area Tam Coc – the "land Halong Bay" and Ninh Binh... Halong Bay (maritime) Cat Ba Island... I’d love to hear your thoughts, advice, and feedback. Looking forward to reading your replies. Cédric

Hello,

Our flights are booked, and we’ll arrive in Thailand at the beginning of January.

Originally, we were supposed to spend 14 days there. But after booking the flights and seeing the prices, we’ll now be there for 20 days instead.

Our initial plan was: 2 days in Bangkok 1 day in Ayutthaya 4 days in Chiang Mai 6 days around Krabi

So we have 7 more days to fill. What do you recommend?

An extra day in Bangkok? Adding more days in the north? If so, where? Exploring another region, like Kanchanaburi or Cheow Lan Lake? Traveling north in stages instead of taking the overnight train?

A few extra details about us: For us, vacation isn’t about relaxation—we love walking, exploring, and packed days don’t bother us. Hiking for hours and doing active things is what makes us happy. That said, we also enjoy visiting villages and towns if they’re worth the detour. In Thailand, we’d like to visit temples too. We’re early risers, so our days tend to be long. 🙂 In short, we like to keep things moving during our trips. 😉

Unfortunately, seeing terraced rice fields isn’t possible in January. I read there are rice fields around Sukhothai. Are they green in January?

In the north, do you recommend Doi Inthanon, Huai Nam Dang, or Doi Chiang Dao National Parks? Which one is the most beautiful and best for January?

Hi there,

My partner and I are heading to Malaysia in early July. We arrive in KL on 03/07 in the late afternoon and leave from KL on 18/07 in the evening.

We’ve planned: Day 1: KL Day 2: Cameron Highlands day trip from KL Day 3: KL → Taman Negara (bus) Day 4 & 5: Trek in Taman Negara Day 6: Taman Negara → Perhentians (bus + boat) Day 7 & 8: Perhentians Day 9: Perhentians → Pulau Redang (boat + bus + boat) Day 10 & 11: Pulau Redang Day 12: Pulau Redang → George Town (flight) Day 13: George Town Day 14: George Town → KL (flight) Day 15: KL + return flight at 23:45

I feel like this might not be the most efficient route. Any tips on how to optimize the order of things (even though I’d prefer to start with Taman Negara)? How’s the best way to travel between places?

Should we book everything (transport, accommodation, activities) in advance, or can we figure it out day by day? I prefer spontaneous travel to keep things flexible, but will there be availability, or will we be struggling constantly?

Thanks in advance for any advice you can share!
