You have received some great advice! My son is 8 and high functioning. Please feel free to read my Trip Report, it's purple in my signature, it is a perpetual trip report as we go frequently. My son always wears a hat to block his view of all the people. He uses a medical stroller/wheel chair as his refuge. We bring post it notes to put over toilet sensors. A flash light or glow stick for if we get stuck on dark attractions. A brush for Wilbarger Brushing Protocol. Wears earphones to block noise, restaurants are where he has most problems. Once he brought a pencil case of the tiniest Lego pieces. He put them together to distract himself. He loves Coral Reef. He is just as happy watching the fish from the top level as he is watching them at window level. We usually eat right when the restaurant opens for either lunch or dinner. Once it fills up, it's too much noise for him even with the ear muffs. Ileonna is our favorite server. She knows us and knows he likes his own butter and extra ketchup. She also is great in how she words what she says to him! We use him for a gauge of what we can do. Go at his pace. We eat at off times so that there aren't so many people around. For example, we learned that we can't go to the F&W Festival on busy nights. He hates darkness and crowds. He did much better on a weeknight with little crowd. We skipped character meals for years because of the expense and anxiety. But recently we went to the Tusker House and the Crystal Palace. Both for lunch, when they just started serving lunch. And it went great! We placed him where he could see the characters approaching, so there were no surprises. I think you'll be surprised at how wonderful Disney can be. My son is very verbal and he says he loves Disney because it's the one place he feels "normal". Where else can you teach Cinderella and Prince Charming how to use the force?
