Yes but the question then comes down to, why wouldn’t G+ have also worked for those people and the main answer that comes to mind is the cost factor. People didn’t want to have to pay.I don't think many people would consider that an equal accommodation by any means, but it brings up how the changes to Fastpass may be a factor.
Three free fasptasses, booked in advance, was probably enough to:
a) reduce the desire to lie in order to get DAS.
b) meet the needs of people with a more moderate disability.
That system generally allowed one to be guaranteed to bypass one or two significant wait times, and bypass some additional moderate wait times. I imagine that would be sufficient for someone who struggles with wait times but is fine with some waiting in line.
