I think the sickness has been greatly exaggerated. We rode it multiple times a few weeks ago. I didn't see a single person get sick coming off of the ride. If I understand how the ride works, I don't see how it could be tweeked. It spins, spinning faster or slower shouldn't have any effect on the sickness factor, it still spins in order to achieve the g's. So, I think the ride is what it is and some will love it, others will become a bit nauseous, but the majority will not be sick from riding this ride and few will actually become physically sick during the ride, IMHO. Isn't that the way it is with ToT, Body Wars, Star Tours, etc? I saw multiple piles of the solution they throw to cover up illness incidents coming off of ToT this past trip. I saw no piles coming off of Mission Space.
