I'm planning a first time trip to France last 2 weeks of June 2023. A total of 15 nights on the ground. My husband and I are interested in going to Paris, Burgundy region, French Alps and French Riviera. This is my thinking so far: 5 nights in Paris, train to Beaune for 3 nights, car to Chamonix for 3 nights. Looking for suggestions on how to transport to Nice and then best way to get from Nice back to Paris. I'm hoping to get direct flights to and from Boston to Paris. Or suggestions on a different route, incorporating the above areas.
