I have an adult son who is autistic. Is there a disabled discount? Would he count as a child for the yearly membership since he is my dependent?

There isn't a discount for the disabled. We are deaf and found out that the film's have sound but they don't have Closed Caption. When we asked we were told only for senoir, military and AAA members.

I know of no such discounts you probably ought to call them

Not sure about disabled discount or the child. If you go to website and check ticket availability they show all the discounts available.
