It also became more unreasonable as crowds have increased and as more people with disabilities began going to the park and accessing GAC. Somewhere, there is a quote from court that GAC users were a small percentage of park goers but were a huge percentage of people riding a popular ride. The rides only have a certain capacity everyday.Well technically this isn't true, the GAC was a workable solution in theory and thus 'reasonable'. If it weren't then it wouldn't have been implemented in the first place. It became 'unreasonable' due to the nature of the process and abuse of its privileges by those that were willing to do it.... which is cited in the Disney Court documents and the article itself.
The reason there is so much ambiguity around the process is the adjudication of the word 'reasonable'...... highlighted perfectly by the discourse in this thread and the subjective opinion of what it means to different people.

"This isn't going to be easy for some Disney visitors to hear. But let's consider this a little tough love. The reason why Disney is ending the GAC program isn't because it was abused too much by people without disabilities. Disney killed the GAC because it was used too much by people with disabilities.
As we've written before, Disney did not intend to create a system that gave visitors with disabilities no-wait, front-of-the-line access to its attractions. That's simply the way the system evolved, for maximum operational efficiency. It simply was easier for Disney attractions personnel to move parties with a disabled visitor immediately onto a ride via the exit, than to make them wait and block the exit area, or to come back later.
Getting to ride without waiting invited abuse, which is why Disney adopted the GAC program, to make visitors with disabilities get a card from Disney so that individual attraction cast members wouldn't have to bear the responsibility of deciding who deserved special access. That helped put a stop to groups of kids renting a wheelchair to skip lines, but the system eventually grew unsustainable."
