My DD and I both rode Mission Space and if you follow the direction and keep your head straight, you shouldn't get sick. I did not get nauseous in the least, but still didn't care for the attraction. I am not one for being closed into anything and you are closed in. I also get this feeling, but not nearly as bad, on Star Tours when they shut the door to the ride. My DD, however, loved it and went on again right after without me. If you aren't claustrophobic or prone to motion sickness, you should be fine on this attraction. Just keep you head straight and do not look side to side. My Passporter doesnt' mention a child-swap just the Space Base playground where they can play while one of the parents ride. You could both take a turn on the ride while the other hangs out here and let's the little play in the playground area.
