Hi. I'm spending a week in Disneyworld next month with my visually impaired, 10 year old son. He is completely blind in one eye and very nearsighted in the other eye. He also has autism spectrum disorder, so I was going to get a guest assistance card. My question is, he needs to sit very up close to see shows (or anything at a distance)- will the GAC allow him to get up front seating / special seating? (The GAC lists several benefits but I haven't seen anything around visual impairment accommodations). I welcome any suggestions! Thanks for your help!
