I have an autistic son, age 9. He is very high functioning, however some music and high pitched sounds upset him and he will fold his ears and whine. What park do you suggest me to start him off in? Also do you suggest Fantasmic MGM? Would we have to wait in line because we cannot get priority seating on The 4th of July week. Will they accommodate us with the GAC pass for Fantasmic so we do not have to wait in line without priority seating? I know I should bring earplugs. My sister wrote a message for me, and thanks to all that responded. I also have a daughter 4 and she is a typical child and I wanted both of there first experiences to be with minimum stress. My son was 2 and too young to remember his first experience.
