As many times as I have been to Disney with my grandmother who rides in one of those (by choice not major need) and as many times as she has not cared where it was going and completely ran me over.....hands, feet and more then once my arm I am very aware of those items. I always make sure they have extra space as I know how my grandmother used to complain about all the bumps. There is something I didn't see in his message though...Please don't cram around the chair and seprate them from the rest of their party. Something that always happened with my grandma is since we were giving her enough room to make it as painless as possible for us other people took the clearence space and piled in. PLEASE, PLEASE, PLEASE don't do that! My grandmother used to panic when she would get seprated from us and it caused alot of undo stress. Thank you!
