This is a very individual thing. I suffer from vertigo & found Mission to Mars (is that still there?) unbearable. Had to sit on the puke benches for about 15 minutes. If the ride has a choice to sit in a non-motion seat, I just skip the whole thing because I don't want to see it that way & there's no way I would exit that ride upright. When I was a kid, I couldn't even LOOK at a carousel in motion, so I try to avoid carousels, the tea cups, anything that turns or spins. But, I LOVE some of the rides that shake you up or drop you, etc. These are rides that some people w/ vertigo cannot ride.
