I have not been yet, so cannot say for certain, however, I can handle coasters and things that bounce and jerk, but not things that spin or virtual motion or IMAX (even some boat type scenes on large movie screens do me in). So, for me, Star Tours, Soarin' - out. I am not sure I would even do it medicated, as my problem is when the motion I see does not relate to what I feel. (And I medicate on the plane - Bonine and Dramamine are both good, Bonine seems to give me fewer sleepy effects) and I want to try ginger this trip.
