Yes, I was on the ferris wheel with my dad for the first time, and the slow way it moved and the way the cars rotated with the movement of the wheel gave me terrible motion sickness. So as a general rule I avoid circular motion rides.
When I was a kid, I was at Pontchatrain beach with my mom. We had just ridden the Galaxy roller coaster, which was an older, steel coaster that preceded the Rajun Cajun.
We exited the ride and walked across the street get in the haunted house line, and after a few minutes we heard a racket behind us. We turned around to see that the very next run of the Galaxy and left the lead three cars hanging off the coaster at the highest part just before the first drop started.
Everyone was able to be rescued, and no one was seriously hurt that I know of, but that was the end of the Galaxy at that amusement park. Really glad we were not on that run.
They get you out at a 45° angle where your butt says you're straight and your eyes says you're not.
Super vertigo city!
