Spiderman is the best dark ride ever built. Its in IOA.
Men in Black and T2 3D are the best rides at USF.
Universal is giving Disney a run their money these days. They don't quite have the magic down, but the are building some amazing e-ticket attractions. You won't regret taking a day to go there. We usually buy a two day pass (not much more than a single day ticket) just so that we can get into both parks (IOA and USF) on the same day.
