The green side doesn't spin at all but the orange side does. We had to use rider swap (b/c our 3 yo wasn't tall enough) and I rode the green side with my 9yo first. It was fun, but definitely not scary or sickening. The tight space was the only thing that might bother you if you are claustrophobic. My husband rode the orange side with my daughter on the second ride because she wanted something more exciting. He loved it and she felt a little 'off' for about 30 minutes after, but nothing too severe. I wish she would have been brave enough to try it with me the first time ;-)
