I tried a search, but of course I got a lot of posts about "nice" hotels in Paris.

I plan to spend about 9 days in Nice in mid-March; I'm considering taking an MBA at EDHEC and want to visit the school for a day, but the rest of my time is free. I'm sure the city will take up much of my time, but what car-free day trips would you guys recommend? I will have an apartment, so I'm limited to day trips. Monaco is definitely on the list; I'd love to explore Provence if I can find a bus tour or something. I am very into wine but would prefer to avoid renting a car if possible. (Wine tasting is always better when someone else is driving, eh?)

Any opinions about EDHEC are also welcome!
