Budget travel · Corsica

I'd love some destination suggestions for a road trip from Nice to Livorno by car, including the routes, tolls to cross, distance, and estimated travel time. We're planning a 5-day trip, with 2 nights near Nice, 1 night along the way, and finally 2 nights in Livorno. There are 4 of us in a rental car, and we'd like to stay in either an apartment, a mobile home near the sea, or a campsite. Our budget isn't too extravagant!!!! We want to visit the Promenade des Anglais, and I've heard Menton is really interesting. Once we reach Livorno, we'll take the ferry to Corsica for 12 days with the same rental car. We're planning to leave the last week of May and the first two weeks of June 2026, so around 17-18 days total. Thanks
