My family is planning a trip to Disney in April. I am trying to plan all aspects of this trip. This includes making it enjoyable for my DS who will be 7 when we go. He as ADHD, Anxiety disorder, OCD, and his doctors are leaning twords an Autism pectrum Disorder. They know he has one, but he is displaying traits that match 2 different spectrum disorders that are closely related and don't want to diagnose him until they know which one it is or if it truly is both of them. His doctors offered to give me a letter to carry with us just in case I made need it. (In case anything happens) I have been reading about a GAC, but am a little lost on it. My son has a hard time just standing (it's not that he can't physically stand. He just can't handle standing still in a place with alot of people it makes have anxiety attacks.) Some loud noises really bother him (I am planning on packing ear plugs, but he also likes to wear the ear muffs like they use in a shooting range. They block out the noise better for him. Will Disney allow me to let him wear these?) I am unable to let him do anything where I am not allow to be with him because that upsets him greatly, and he doesn't communicate well with children his own age. What exactly could a GAC help us with? I don't expect them to let him cut the line, but what do they mean by letting him go to a quiter area? Is it a sit down area, or do you stand there too? Does anyone have any ideas on how I could make the waiting time easier for him? If he has to wait more than 5 minutes for something he starts displaying his anxiety, and wants to fidget due to the ADHD. any help would be appreciated.
