I'm just going to go ahead and say it:
If you use a wheelchair, cart, crutches, GAC, etc. to get around Disneyland, I have no problem with you going through the exit. But you should have to wait the minimum of the posted wait time for that ride.
If the sign posted says 60 mins, you have to sit there for 60 mins and wait your turn. Sorry, but maybe this will make things fair for everyone!
