There are several.
Stitch, because I've heard enough stories about that belch to be pretty sure it would make me sick lol
Barnstormer, just not something I'm interested in.
Space Mountain. I've thought about it many times. It is the only mountain I've not done, but the many many posts about how rough it is keeps me away. I have a bad back, and I'm not really interested in missing several days of my vacation because of it. Too much thrashing around and that is exactly what will happen. I came pretty close to that riding the safari in AK one time, had all I could do to stand up and get out of the ride vehicle when it was over.
Dinosaur for the same reason as Space
Astro Orbiter, because no doubt, there would be a protein spill.
Alladins carpets, and Dumbo . . . very likely would end up the same as Astro lol
Rock N Roller Coaster. I will do this one eventually
Tower of Terror . . oh h e c k NO lol
