Come to the disABILITIES Board (there is a link in my signature).
We usually have several active threads on the board about seatinng for shows like Fantasmic.
The last row in the whole theater (right behind the last row of benches in the theater) is parking space for people with wheelchairs and scooters. The two rows of benches right in front of that are reserved for guests with special needs who don't have wheelchairs/scooters and the parties of thosee groups.
