Travel with children · Montréal et Laval

Hi there, I’d like to plan a family road trip (2 adults, 2 kids aged 14 and 11) next summer, starting in New York and ending in Montreal. Here’s my rough itinerary: Arrival in New York: 4 nights Train to Boston: 2 nights Car rental, then off to Cape Cod: 2 nights Head to Acadia Park: 2 nights On to Quebec City: 2 nights Tadoussac: 2 nights Saguenay region/Lac Saint-Jean: 2 nights Montreal: 2 nights Departure from Montreal. Could you share some ideas for places to stay, eat, visit, whale watching, lobster feasts, etc.? Also, about the car rental: picking up in the US and dropping off in Canada—any tips? Would it be easier to fly round-trip from Lyon to Montreal and drive to NY instead? Thanks for your feedback!
