Hello, we are flying in to Nice from Paris early September and are going directly down to St. Tropez for a few days, then returning to Nice for a few days. What's the best way to get to Nice from St. Tropez? Is there a train? if possible, we'd like to avoid renting a car. Can we hire a driver to bring us there and back? Does not matter if it's not the same driver. Can we go by boat? Approximately how long will it take to get there? any/all help is greatly appreciated. Thanks!!
