I come to Dis Wld with my nephew who is 32 yrs is ASD, OCD, BiPolar, mild MR, ADHD, and has GERD. He is on meds and can not be in sun/heat extended per of time. He is not in wheel chair and therefore does not always appear "handicapped" until we get in a line! After a few min he is pacing talking to himself and getting in peoples space. We have letter from Sheppard Pratt hospital Dr. describing his special needs including pre boarding on a plane. We do give letter to CM at guest relations when first entering a park and get GAC which we do not use unless necessary. We come in Nov. or end of Jan. to avoid crowds and heat. Usually hav minimal waits during these times butn can only 2 attractions before he wants to go back to pool. Love fireworks dessert party only way we can do fireworks other than sitting on bench outside entrance of MK. Sometimes having the GAC allows us to visit additional attractions. I would be more than happy to give anyone questioning our use of the GAC the opportunity to take my nephew and the GAC and I will take their child and be happy to stand in line.
