We have 4-5 days to get from Nice to Paris. Do you recommend driving or taking trains? We are looking for suggestions for a route to see the countryside and small towns, Arles and Avignon, a winery or two, and a castle or two along the way. I suspect that's not as much time as it sounds. I've read the advice not to try to see too much and save some for the next trip. So all advice is very welcome.
We will be there the beginning of July. Should we make reservations for lodging along the way or can we leave room for a couple of nights of travel spontaneity? Thanks.
