In no particular order, all at the World:
Rockin' Rollercoaster
Tower of Terror
Kilimanjaro Safaris
Expedition Everest
Space Mountain
All roller coasters for me with the exception of one as I tend to be a bit more of a thrill seeker. That's not to say I don't like other attractions, but they tend to be the highlight for me after a long day in the park. Kilimanjaro Safaris might be my favorite overall though.
