So it sure sounds like
DAS was denied and they were told to utilize Attraction Queue Re-Entry (AQR) instead. Which does not require pre-approval and is available to anyone. This tracks 100% with a bunch of first-hand reports I’ve seen today from people also being denied DAS and told to ask CMs at attractions to utilize whatever exit & return system that attraction has in place.
I also saw a first-hand account of someone using AQR at Peter Pan yesterday or today: they told a CM they needed to exit to use a restroom, their party stayed in the SB line, and upon their return the CM sent them through the LL to wait for their party at the merge. No diagnostic details were involved: they just said they needed to use the restroom.
My point in laying all of this out is that with more and more reports coming in, it really does look like the goal is to spin as many as possible off DAS by asking them to use AQR instead. Which might be great for lots of people, or at least good enough… but the splitting up of families to make that work is disappointing.
