Or, the system is set up to keep those from needing "a little help" from getting the help. I mean, who couldn't use "a little help" from time to time? The purpose is for those who genuinely need the extra assistance to get it. I have a terrible knee and hip issue. They really really bug me from time to time. Would it be nice if I never had to wait in lines? Sure would. Would I ever get a DAS/GAC for it? Not in a million lifetimes. Now this is not the mindset of a large chunk of users out there. They would get the DAS/GAC in a heartbeat. To get such an advantage would be a pride point. While, for others, not getting the DAS/GAC is a pride point.
Disney is simply wanting those who NEED it to get it instead of those who WANT it. Parkinson's, totally justified. It is not a cute disease like Michael J Fox makes it out to be. Why it was rejected is beyond me. Perhaps a bit more explanation of the symptoms is necessary?
