I don't get motion sickness. I don't get car sick. I have never in my life gotten sick on a ride. Until Mission Space. The entire time my DH and I were in line, I was worried about him (he does get motion sickness). I was laughing about how I was going to have to hold his bag for him... Boy, if I only knew. During the ride you make a trip to Mars, and all I could think was, if we have to flyback to earth, I'm going to throw up. Luckily, there is no return trip, but I didn't feel well for about 45 minutes after (kinda headache-y and nauseated). And my husband- was just fine! (p.s. - I'm 24, he's 26).
