Thanks for all the great ideas! I have been to and loved St Paul de Vence, Grasse and Villefranche-sur-Mer as well, but not the other places. Do you know if SNCF buses or trains go to any of them? While I have rented a car in France in the Loire and Dijon, I was able to get an automatic. I can't drive a stick shift, and definitely would not want to try the heights!
