Here is a list of where I have stayed and my thoughts about them:
Polynesian - My All-Time Favorite, Can't say enough about it.
Contemporary - As long as you are in the tower, it's great. New rooms look AWESOME!!!
Grand Floridian - Too high class for me but VERY beautiful
Wilderness Lodge - Great place, but for money I want the Monorail
Carribbean Beach - Too spread out but nice
Corinado Springs - Too spread out but nicer then Carribbean
All-Star Music - Not even worth it when you have stayed at all of the above.
Of all of the others I would have to say that my favorite resort that I haven't yet stayed at would be Boardwalk. I Love the theme and location and ease of getting around to all places.
