Poseiden, Pteranodon Flyers (75 minute wait for this???), and Twister. Caveat is that I had high expectations for Twister and it did disappoint but it really isn't all that bad. Poseiden ... boy, I asked the attendant what it was and he said it was a "walking special effects show". I walked in expecting special effects and the water tunnel was the only thing mildly interesting.
I love the movie Twister (I probably watched it 10 times) but the ride itself was not well done. They would have been much better off going 3-D with the attraction (much like Spiderman) and having you go through the town as the twister is hitting. How cool would that have been?
For P-Flyers, it's because there are only 3 birds, and 2 people per bird. So only 6 on the ride at a time. That's why there's no express on this. Can you imagine what the standby line would be like with express?!
