Thanks everyone for your info. We had a great time and Christian did much better than We thought he would do! I carried his cooling vest with refills both days and he never needed it but the water bottle idea was perfect! We used the hat with the long back and that was invaluable! So was going spacing inside activities with outside ones! I left before I got the handicapp pass idea! I will definately use that next time! Thanks again everyone! I don't know what I would do without your help!
