If you like thrill rides, here is my list. We were just there last weekend.
US: Rip, Ride, Rockety, Mummy (my favorite), Simpson (awesome), Men in Black, Shrek 4D, Disaster (closed when we were there but I heard it was good).
IOS: Hulk, Spiderman, Dr. Doom, Dueling Dragons. Water rides if its warm- Popeye's Bilge Barge and Ripsaw Falls.
We didn't see any of the shows but I hear the Make up show in US is good and the Sinbad anad Poseidon shows are good too. If you are there when Harry Potter is open, then that should be awesome!
We were just there for 3 days and had a great time. We stayed onsite, so our room key was our express pass but it really wasn't crowded at all. I think the longest wait was 60 min. for Rip, Ride, Rocket and 25 min. for Spiderman.
An hour wait??? Oh goodness you have me scared and that's when it's not busy?
We are going the last week of March. I'm getting the 4 day two park passes for the four of us. We LOVE thrill rides as does my son. But my dd is going to be too small for them i'm sure.
Storm Force and Dr. Doom are skippers for me. In US the only one that is a waste of time for me is Disaster, but you should do it at least once if you've never done it before. My wife's least favorite in US, is, believe it or not, Shrek.
The ones we don't miss are Spiderman, Hulk, Popeye/Bluto if the weather cooperates then Simpsons, MIB and Terminator in US.
In a class by itself is Hollywood Rip Ride Rockit because it's just too unreliable now. If it's running and the line is reasonable we'll go on it. If we're pressed for time it's a no-no.
As unlikely as this may sound, out of all the thrill rides in both parks the only one that makes me the least bit queasy in the stomach is Cat In The Hat. Something about that whipping around just doesn't agree with me, but I still go on it most times we are in IOA. Next visit we'll have small children and FOTL so I'll probably ride it 50 times. Maybe I'll get some Dramamine
