I have yet to get sick from riding one but I do get an upset tummy every time I ride Mission Space. We live in Florida, we have annual passes and it is my husbands favorite ride. So, needless to say, I've been on it alot. I have to do labor breathing stuff to get through the launch without getting sick. But I do always feel like I'm gonna be sick at the very end with the whole cliff drop thing.
My husband feels sick on Tower of Terror. Now, that is my favorite ride and he won't ride it with me. He did once on my birthday and that was it. He wanted to sit on the side so he could hang on. I always sit in the middle so I have nothing to hang on too. I love it. My bootie goes way up in the air!!! Wheee!!
All three of my kids love the teacups. So being sick on them is not an option. The ride has to be done.
