Motion sick on 3 somersaults in a pool. You are a wimp!
At Disney World they have one ride called the trip to Mars. I was sitting in a "Cockpit" type setup with a buttons and a little monitor to watch. No outside visual reference at all. It is all indoors. They have some amazing motion and effects. The blastoff is a lot of vibration and acceleration but they somehow do a weightless sensation and lots of motion as we dodge asteroids. It was very juvenile but fun. In the line to get on they had a LOT of warning about motion sickness. For sensitive folks they had a less motion version. I went on the full version. I would have doen the ride again but my wife would not even go into the building much less ride it. I did not want to make her just sit and wait.
I don't ever remember being motion sick.
