While in the past there has been a lot of abuse of the disability policy, I can tell you that this year it has greatly improved. Having personally taken someone around the park who has a disability and is wheel chair bound, I learned first hand how the system has greatly improved. First off, you can no longer just go up to the exit of a ride and hop on, you first must visit guest relations and receive an Attractions Boarding Pass. There at Guest Relations, my friend notified them of his physical limitations and they helped him consult on what would be recommended for him to ride and what wouldn't, then you receive your Attractions Boarding Pass. This pass allows you to go up the exit of a ride, however, once you get there you must present the pass to a ride attendant. If the line is under a half an hour they will let the person with the pass and one additional rider (until this year it was three additional riders) board the ride. If the line is over a half an hour they will write you a time on your pass, stamp it, and you are free to come back at that time (Note: you can not have any other active times written on your pass when you go to get a new time, in essence: you can only wait in one line at a time). Now if you have more than 2 people in your group, you can have your group wait in line while the person with the pass and one other wait at the exit, then just notify the ride operators and they will help you all get paired together, thus everyone waits an equal time.
I was really impressed with how the system was executed this year.
My wife was wheel chair bound for 4 months after foot surgery..when we went to Top Gun we were told they would stamp that paper and we could come back..which we told them never mind...who wants to make two trips clear back there. Maybe if they had an employee at the entrance of the queue.
For rides with long lines (not waiting time, but physically long) like WWC and Flight Deck this would be a great help. Who wants to walk that distance four times?
