I have read some early reviews about the Avatar Flight Of Passage ride that are saying some guests are being turned away due to the ride restraints not fitting. Is this true?

Apparently there are multiple restraints and while some people have had no issues with "upper" belts, some are saying the leg restraints aren't fitting...and the other way around.

Also hearing there is no "test" seat available before getting in line for the ride. It would be awful to wait hours in line just to be denied boarding.

Anyone else know about this?
