I rode it and got sick, but I am prone to motion sickness. Star Tours, and especially Body Wars can trigger motion sickness for me. I did keep my head back, had read the warnings. Truthfully, I didn't feel normal again until the next day! However, I didn't take any medication in advance. I will when we go in December. I was bummed because the ride is neat, and I'm a thrill ride junkie. I suspect that the spinning of the centrifugue which generates the forces is what does it, even though I couldn't feel the spinning at all. Spinning and side to side sway type motions are what are most likely to make me sick. Coasters, fortunately, don't usually do that.
