if anything, disney tends to over-warn.
the first time we rode alien encounter, we stood in this massive 2 hour line out in the hot sun (this was back when alien encounter first opened).
all through the line there were warnings about people with dizziness and back and neck etc etc etc. At the front there were huge signs with warnings. So many in fact that i finally chickened out.
Later in the day, we were on the bus chit chatting with another family.
They mentioned alien encounter, so we asked them if i would have a problem.
They laughed. Said the attraction doesn't even move. That it would be no problem.
So we went back - stood in that ridiculous line again - and did it. And loved it by the way. Bring back alien encounter!!
Anyway, that was a case of over warning. And they do that on all their rides.
So for him to say there were no warnings is ridiculous!!!
