I am coming to France in August spending 6 nights in Paris and then flying into Nice with my wife. My original plan was to spend all four nights in Nice but now I am wondering, do I spend two nights in Cannes and then two nights in Nice. The reason for my debate is we really want to spend some quality time at the beach and if the beaches in Nice are rocky, maybe we should save those last two days for sightseeing in NIce. I am curious of peoples opinions. Thanks!
