Okay, instead of just my favorite rides, here's my LEAST ones too:
Universal Studios
Most favorite: The Mummy, and maybe Jaws but it's highly depends on your skipper
Least favorite: Men in Black. Although it is interactive, methink it's overrated and not a bit thrilling. Why do guide books rate it as thrill ride? Cause I don't think so.
Island of Adventure
Most favorite: Spiderman. The Hulk comes close.
Least favorite: Dueling Dragon. I liked the theming and even loved the dragon souvenirs, but that damn thing hurt all of my party member's head. We had serious headaches and were a bit disoriented after riding it. Btw, we rode Fire.
