Howdy!
We just got back on Sunday (8/28) and sat in the Handicapped section by those two shops near the entry of World Showcase. Like a previous poster mentioned, PLEASE watch the wind direction when choosing your spot! We had a TON of fall-out from the fireworks and literally had a shirt ruined from the burn marks! My 9 yr. old DD got a piece of debris in her eye. We were coated with ashes. It really ruined the show, not to mention concerned for everyone's safety! I didn't even think it was that windy of an evening. Also, unless the rest of your party is willing to sit on the ground by the wheelchair, you won't be able to sit together. If I had to do it again, I think I'd just find a good spot around the Lagoon that wasn't designated specially for handicapped seating.
Have a magical time!
