One that I've never stayed in but would not like to stay in is Caribbean Beach. To me its just way too big with too many bus stops etc. Nice for the Skyliner but I'm not one to just enjoy wandering around the resort because I'm in the parks most of the day so I just want to be able to get back to my room.
Ones I have stayed at and am not a fan of...
-Art of Animation: I stayed in a LM room and its just too much of a walk to the main building and I find the food court smells and is very loud.
-Coronado Springs (have not stayed in Gran Destino): had several things happen while staying there from them losing my luggage, to not activating my KTTWC, rude waiter, etc. And the bus Transporation was terrible.
-Grand Floridian: Not worth the price. The rooms were just OK, I didn't vibe with the atmosphere.
You didn't ask but I'll give my favorite resorts as well.
-Pop Century: love the theme, the paths are pretty direct, transportation has always been top notch!
-All Star Sports: its always the cheapest of the Values and there is nothing wrong with it so if I'm going on the cheap its my go to!
-Port Orleans Riverside: its beautiful, the rooms are nice and pretty sound proof, boat to DS, great food!
-Contemporary: monorail, relaxing, close to MK, the garden wing rooms are pretty sound proof.
-Polynesian: love the theme, love the food, close to MK, on the monorail, relaxing.
