I wish I could say it was me (big sigh), but have only been to 5: Fort Wilderness cabins, All Stars Sports, All Stars Movies, Dophin, and Port Orleans Riverside. So far, I like POR best for resort atmosphere, Dolphin best for location. I think the fun is trying out different ones, rather than just staying at the same ones, and my goal is to stay at most of them. There are a couple, such as the All Stars Music and Pop Century, that hold no appeal to me.
As a consolation prize for not staying at the resort, we usually arrange to dine at the resorts at least once a trip. The ARtist Point to check out the WL and O'Hanans to check out Polynesian and Chef Mickey's to check out the Contemporary. Have discovered some excellent restaurants in the process and then feel like we've stayed there.
