It seems important to always clarify what we mean by a disability.
Accommodations for *rides* have varying levels of accommodation: some rides allow a mobility device; some rides require a transfer; and some rides have no accommodations at all.
But, with DAS, we're focusing on the accommodation for *waiting in line.* And that can be a totally different type of accommodation. E.g., there are those who don't need any accommodation for the ride itself, but they need one to not wait too long in line.
It is plausible that there are those who can wait in line, even though they have some sort of disability. E.g., there are those who can tolerate a long line while in a mobility device. They don't need a DAS accommodation, because they can tolerate the wait. Thus, even though they have a disability, they don't need DAS. But... they might ask for one simply because they presume that DAS is for them because they have some sore of disability.
Then there are those who are frauds and claim they need an accommodation from long lines, when they don't need the accommodation at all. That number seems to have become very problematic.
So, how do we get the right accommodation to the right people for the right circumstance?
The interview is to weed out frauds, and also those who, in good faith, thought the DAS accommodation was for them because of a disability, but, didn't realize it was just for those who can't tolerate long lines.
Now, judging who can tolerate long waits and who can't based on their disability is the real sticky point in this.
