The problem with the phrasing about it being for other people's comfort is that accommodations are not supposed to be about what makes a non-disabled person comfortable. I've met plenty of non-disabled people, even now, who were not comfortable with having me in the same lines as them just because I use a wheelchair. That doesn't mean I qualify (or should qualify just based on that) for a DAS. Accommodations are for disabled people for their needs and safety. As well, the phrasing suggests that the DAS is only supposed to be for when the effects of the disability impact other people in the line. There are plenty of reasons why someone might need a DAS (and qualify based on the rules) that have nothing to do with the experiences of others in the lines. There are plenty of reasons someone could qualify for the DAS that aren't sensory related, as well.
AMEN! That's exactly what I think.
