My husband feels sick after Star Wars, teacups, etc and I do not. I don't like the falling feeling in Tower of Terror, it does not bother him at all. Mission Space bothered him and did not bother me at all (I loved it). So if you are bothered by the same rides as my husband ,you probably will not love Mission Space. It is a very quick ride. I think only very sensitive people would get sick on the ride, but you may feel awful after.
