Very well set up for the disabled.
They have disabled services everywhere and most states have special seating and areas to accommodate wheel chairs. In order to stay open they must follow the ADA law; American with Disabilities Act. You may want to Google this.
They do a good job with some of their rides by providing special access and assistance into the ride. No pressure trying to negotiate the sometimes frenetic ingress/egress of some of the rides. You may need to notify an attendant at the entrance to prepare staff for the assistance needed.
For most of the shows they have good arrangements for people with wheelchairs.
Actually, now that I'm thinking about it, thay had good facilities for disabled peeps, e.g. they had platforms in the orcas/dolphins theaters where wheelchairs could park and enjoy the show. Same thing with the penguins and the others. Except for the instance with the Atlantis show where the people were standing, so it could be difficult to see unless you're in front rows.
