Minuet888: During quiet(er) times, your son may not enjoy the ambience - when it is crowded, I am certain he will not like it. He IS welcome to be there, kids are allowed in there, they do not serve alcohol there. That being said, it has a very high ceiling, and the echo of the voices is very noticeable. It is also very dark in there. A great retreat on a really hot day, but then of course it is crowded and noisy, especially before a show. Your son may really enjoy going to Disney Animation Studio at California Adventure Park, he can watch some movie clips on a big screen while he waits for an event to start. He may love to go into the animation studio to learn how to draw Disney Characters, or, he may love seeing Crush the Talking Turtle. There is also an area to explore that tends to be more quiet and less crowded, things for him to get his hands on and see spinning films, etc. He will also love the Toy Story attraction that spins around and looks REAL as it turns faster and faster. VERY cool. Just remember to keep him even more well fed than usual, it is hard and draining on these kids to walk around the way so-called neurotypicals do, and the less droopy his blood sugar levels go, the easier it will be on all of you, including him. Also, mid afternoon nap or at least a rest, or swim, is beneficial!
