I am not the OP, but I did not read anything that was an attack on a protected class of people. I believe what is being said is that
DAS is not required by law. That is an extra that Disney offers, however there is nothing state or federal saying they have to. If there was, it would be offered everywhere. Movies, stores, malls, many places of entertainment, etc do not offer DAS or anything like it. Disney is required to follow the ADA, which they do. Granting people access to skip the lines without a fee is not required and it is not discrimination not to do so.
