We are planning a trip in late June/early July to join my daughter who is studying abroad. We meet her in Milan and then are thinking of a trip along the coast through France including Nice, Cannes and ultimately to Barcelona. I have lots of Marriott points so am thinking about booking Marriott hotels along the way. I am also wondering on trains versus car rental on the trip. Are there train routes along the coast route we are hoping to take. Any information would be greatly appreciated on hotels (especially marriotts) and how we might travel (cars versus trains). We are looking to spend around eight days or so.
