My autistic son is 4 years old. We have taken him to Disney twice (his past 2 birthdays). We learned many lessons on our first trip, so we were well prepared for the 2nd! He is a "sensory-seeking" autistic, but he is bothered by the close proximity of guests in line and waiting for more than 5/ 10 minutes. The guest assistance pass is a godsend and this year we did use the stroller as a wheelchair, because it blocks out all of the noise and views of the crowds. For our first trip, we didn't do this and he pretty much tried to rip down the gates surrounding Dumbo as well as come 3 inches from throwing himself onto a boat in Living with the Land. The stroller, which was his own from home, provided the sense of security he needed with all that was going on around him.
Disney gives him just the right amount of stimulation that by the time we eat dinner he can ALMOST behave at a restaurant. He watches all of the planning videos and movies during the year. During our first trip, he was frightened of the characters, but for this past trip, he did go up to them. He's very, robotic about it. There is no true emotion, they sign the book and say cheese...that's it, but it is such a milestone for him socially.
Since we returned in November, he is now "greeting" everyone. His speech therapist is amazed at how well he is doing. He is making eye contact and doing parallel play at his peer group sessions. Do I think that Disney has alot to do with it, yes. It's quality family time and alot of one on one time with him. There's no fears, mommy & daddy can be just like him and relate better that after a hard day at school and work. I think there are so many factors that make the trip enjoyable.
I never realized that there were so many other parents of autistic children here at wdwmagic. We should start a fan/ support/ tip group!
