I'll be taking a train from Genoa over to Nice and will be in the Côte d'Azur for 6-7 days before flying out of Nice. I'm torn between having a home base around Nice and just exploring Villefrance, Cap Ferrat, Menton, Cannes, Antibes, etc...or renting a car for a few days and driving over to Cassis, Aix en Provence, Nimes and Arles, Pont du Gard....maybe Bandol, Cassis, Six Four Les Plages...?
I know it's possibly to take a train, but am reluctant to do so all the way from Genoa as it seems a long trip (6-7 hrs) and one way international car rentals for one day are super pricey...and sometimes not even available....ultimately, I wouldn't mind taking a train over to Nice from Italy, then renting a car and driving west into Provence...I've looked into renting a car, but can't seem to get a consistent price.
Any suggestions, guidance or ideas would be much appreciated!
