We have ridden just about every ride in all 4 parks at least once through the years. We don't know for certain it will hurt or make us sick. We don't ride Star Tours any more but did a few times when it opened, even rode that darn Body Wars back in the day a few times. He has nerve damage in his spine and as long as it's not bumping or jerky, he can do pretty well. He can ride ToT, BTMR and even Splash but not SM (I can't ride that either) or RNRC or EE. I've read most of the reviews and it seems it's not too jerky and the back coming up should support his back. As far as getting sick, we are going to pay our penny and take our chances, won't know until we try it. We will most likely ride it late in the evening so if does hurt his back we can just go back to the resort. I offered to not ride it and he was adamant that we have to at least ride it once (grown man of 37 so he knows his body).
