A DAS user doesn’t have to be a “fraud” for this to be still be a systemic problem. Part of the problem here is obviously that people are getting an accommodation that interferes with park operations when a different and less demanding accommodation is possible. This is why things like a “return to line” pass are a reasonable accommodation for those whose disability prevents them from standing in lines for a long period of time without a break (versus those who are neurodivergent and literally cannot wait in a long line). Then there’s the soft abuse already mentioned here, when those who legitimately qualify for DAS nevertheless “maximize” it to such an extent that they are using it when they don’t need to. Things like a DAS user who uses DAS to skip a 15 minute peoplemover line, not because they really can’t wait in that line (they just waited in a 20 minute lightning lane+after-merge line for Soarin the day before) but because they have the service, so they use it.
In the end it doesn’t really matter whether it’s all abuse. What matters is that the system as a whole is unsustainable. As DAS usage increases year over year (that tripling stat is eye-popping), more and more of overall ride capacity will go to DAS and less and less will be available for everyone else. Each individual DAS user may think “hey, I’m only adding a minute onto everyone else’s line, and they’re all jerks for questioning that”), but in the aggregate every ride only has a certain amount of throughput every day. DAS is currently on the trajectory that, if unchanged, nearly all of that throughput would go to those within the DAS ecosystem, with very little left for everything else. Something had to change, and this is why Disney is doing this.
