After planning this holiday, I realize that we will be in Nice on the National Holiday and I'm wondering what to expect. I suspect that trains/buses will be on overload so I was thinking we should stay within walking distance of our hotel which lies a short walk south of the Thiers train station. Will key sites like the Chagall and Matisse museums and the monastary in Cimiez be open? I know it will be a bit of a hike, but I was thinking we could talk to these. Since the holiday falls on a Sunday, are things likely to be closed the next day on Monday? Will restaurants be open? Are there special events like fireworks?
