Not exactly. You get 3 FP+ like any other guest, but with a
DAS pass if you walk up to a ride without a FP+, they give you a return time corresponding to the time of the standby line. So if you have no FP+ for Peter Pan, and you come up to the standby line with a DAS Pass, and the Standby line is 45 minutes, you will get essentially a FP+ for 45 minutes from when you arrive. What you do for that 45 minutes is up to you, as opposed to standing in the line.
So you still have to wait the same as any other standby guest, you just don't have to wait in line.
What they are asking for changes depending on the Plaintiff. Some of them want to be able to make out a schedule before they get to the park of when they can do every ride, or however many as Disney will justify, and at what exact time they can go to the front of the line.
Other plaintiffs are asking for immediate access to any line they come up to, because their disabled guest simply cannot wait any length of time because of medical reasons.
Other Plaintiffs have asked for other accommodations, or made suggestions. So this suit is a compilation of things, some of them complimentary, some of them contradictory, and all of them saying what Disney currently does is not good enough to provide them with the same experience as other guests.
And I really hope that everyone reads these as neutral statements of fact, because I truly am making no opinion on the merits of any of this. My family is fortunate enough not to need these kinds of considerations and I really can't imagine the challenges for the families that are asking for them.
