I see more people in the the Disney Land hotel lobby checking in with those temporary strap on foot casts than the number "injured/crippled" people checking into all other hotels I have checked into combine. Rent a wheelchair, and wha-La! access to the wheelchair access lines.
Yes, people from all socioeconomic backgrounds can be selfish assholes. I guess for the rich it is worth $1k+/day so that they themselves don't have to appear handicapped.
From what I understand Disneyland used to have a problem with groups of teenagers renting wheelchairs to "cut" in line. I believe that they have curbed that.
