There are two places for nightlife at disney. PI, which has 8 or so different themed clubs and a sometimes crazy crowds and the riverwalk, which is a really nicely put together new england turn of the century type area with restaurants and shopping and clubs. Jellyrolls is on the riverwalk. It is just a type of club that a lot of seasoned disney folk go to...lots of fun...but at disney, what isnt? It is one of several clubs there but be warned they are a distance from each other. If you have kids and are doing something for just a couple of hours alone pick one and stick to that. If you are going all night then check both out. We might just see you there. 80's club at PI is my favorite.
ENJOY
