I’m probably in the minority but I’d love that change also, I love the ride but it’s a once a day for me because it always makes me queasy.
With 4 theaters this is one of those rides where they could easily offer both a 2D and 3D option, similar to how Mission Space has a non spinning side to prevent motion sickness, the fact they don’t makes me think I must be part of a very small minority that it makes feel sick.
I really don't know why Disney doesn't provide 2D glasses for anyone who wants them. They just have to have the same lens in each eye so they're receiving the same picture
