Gotta be Wilderness Lodge. I mean, I like the other resorts, but many of them are tropically or beach themed (BC, YC, BWV, OKW, CBR, Poly, etc.) How hard can it be to make a place in Florida look like, well, a place in Florida?
On the other hand... make me feel like I've just stepped off the bus/boat and right into the heart of the mountains, like I'm in a magnificent pacific coast lodge, and yet STILL be smack dab in Central Florida -- you've really accomplished something magical!! And Disney is all about the magic, for me!
Plus, I happen to LIKE that woodsy forested a-river-runs-through-it lodge feelin'.
As for least fave -- probably Contemporary. It's just too dang hard to stay ahead of technology, and that toaster looks mighty dated (and the room decor gives me retinal fatigue.)

It's such a shame, too -- what a great piece of real estate. I tried once to argue with DH that we ought to try it for the views outside a tower room... his comment was, Yeah, but then I'd have to turn around and see the view INSIDE the room. (I'm pretty sure he meant the aformentioned wild array of "contemporary" decor colors, not me... or at least, that BETTER be what he meant!
