We are 2 retired couples, over 70. We'll be staying in a Nice apartment near the Hotel Negresco from 23 Jan to 5 Feb. We want to take a day trip to see the Annonciade museum in St. Tropez. I understand boat rides are not available this time of year. How can we get detailed info on train schedules to St Raphael and connecting bus to St Tropez? How long a walk is it from the bus stop to the museum? Is there a restaurant within walking distance for lunch after the museum visit? And, of course, is the schedule for bus and train transit back to Nice available? Many thanks for help with this.
