None. But a couple of them need 3d glasses to be worn. For some, wearing these glasses could cause dizziness. Plus, these glasses are not cleaned properly and have scratches in them, which make viewing straineous at times.
Quite a few if you get motion sick. The forbidden journey ride for Harry Potter is quite disorienting if you don't like being spun around almost on your back and then around again. I usually don't get that motion sick on rides, but tht one almost did.
Agreed with above comment.
They are all over so quickly that you don't really have time to get sick
Yes they do require 3d glasses but the only one that I've seen get people really sick even the Orlando location is the same is harry potter that is definitely the worst one
