Best disney world resort?

I'm going with 6 people, so I'm going to need 2 rooms (which i prefer; my son, daughter and her boyfriend want their own room). Anyway, I'm thinking about the Animal Kingdom lodge because of the safari theme and it's not that costly; the Contemporary resort because of the modern interior design; the Yacht club because of it's atmosphere and there's a lot of recreation there! The boardwalk resort is also nice and has a lot of recreation too. Which one do you guys perfer?
