@cicerone imposter,
My friend is a diver, so Jacques Cousteau will certainly be of interest.
I'm not all that much into palaces...i prefer ruins when it comes to castles and such, but i can be a good tourist for a day or two. otherwise i prefer the coffeeshop kind of tourism, preferably with the natives, ultimately just sinking into the local life for a few days. but....don't know anyone in Nice.
