My understanding of the DAS pass is that it is given based upon what problems you have with the normal queues. Things like parades, WOC, and Fantasmic do not have queues so therefore, DAS does not work for them.
My DD utilizes a DAS pass. For parades, we find our spot on the curb early. For WOC and Fantasmic we will do the dessert party or the dining package and get there early for the seats we need. We have learned to make our own accommodations with those attractions. That said, there is a “handicapped” area but it is mainly for individuals in wheelchairs.
