They have two kinds of accessibility passes. The first pass allows you to go to a ride and have the attendants give you a return time to get on the ride, much like the Disneyland Fast Pass. The second pass is the General Assistance Pass, or Gap Pass. That gets you to the front of the line if the wait is over 20 minutes and it works for rides and shows. It's harder to get that one when the park is super busy during peak attendance.

I've been to the Hollywood one twice since going blind and have always gone with my sighted partner. I'm thankful that I had visual context to the park and some rides that I got to go on before I lost my vision, but everything is fun, the food is quite tasty, and I'm sure you'll have a good time. I think they have some scripts for shows in braille at guest services, but I didn't check those out, and I don't think they have an audio description service. Highly recommend the Klogger Burger from Krustyburger by the Simpsons ride and butterbeer from Harry Potter world.

I chaperoned a trip to Universal Studios LA with about 25 blind high school students. They all enjoyed the rides and the chaperones provided audio descriptions when necessary
