I tend to get motion sickness when you get the double spinning thing going. So I was really nervous about riding it. My DS(19) rode it while waiting for us to get to the park. He couldn't tell me much. He kept talking about how they keep enforcing the motion sickness part. You wait in line inside the building 1st looking at some big wheel thing turning. Then they put you on some circle number like they do all the other rides based on the number in your party. Then you see a short movie (i think). Then the doors open to another area and you go stand on your same number again. Then another door opens an the people in your group after seeing a nother short clip explaining what everyone's task is on the launch. You get inside the actual ride. The screen displays come towards you which could make someone with claustifobia(SP?) scared. It didn't bother me. My DS said the best thing to do was to concentrate on your task during the flight. So I did that and messed with the buttons on the display in front of me. (Your button will light on your display when it is time to do your task). No need to worry about that. I have a fear of heights to and when the ride took off you could see what looked like the sky, so I concentrated on the buttons and stuff. I didn't feel that much of a G-force. I was actually disappointed in the ride. I get more of a thrill riding TOT. So since it didn't impress me much I only rode it the 1 time and didn't get sick at all. If you need to know anything else, just let me know and I'll see if I can help.
