You do move, you sit in a "capsule" and the "spoke" of a wheel. You are completely enclosed, but the way the get they feeling is to spin you around the spoke.
You may feel sick. I felt queasy about two minutes after getting off, but not at all on the ride - and I stayed queasy for a few minutes (nothing compared to morning sickness!). The ride is only four minutes, and I don't think you are "spinning" the whole time (I think the capsule rocks as well - like Star Tours - and you are looking at a little screen - like Star Tours, but smaller).
You should keep your eyes open and facing straight ahead. This will help with queasiness.
It was a fantastic ride. No one I saw coming off was actually "sick" - although I think other people felt a little queasy.
If you do decide to try it, have some soda crackers on hand to calm your tummy afterwards - and don't ride after a big meal. If you are anxious, go to the end and watch people coming off.
