I think that Disney doesn’t want to put the exact formula for what accommodation is available at each ride under each circumstance on their main attraction pages or MDE information because it makes more people who can wait in lines but don’t want to start thinking about how to “beat the system” instead of actually being available as a resource for ex-DAS users. If, hypothetically, one knew that Peter Pan typically just directs you to the LL when the wait is less than 45 or issued a LL return pass when the wait is more than 45m, a lot of people would tell the attraction CM “gee whiz, I would just love to wait in this here 75 minute line but I sure can’t, what can you do for me?”
I (obviously) don’t speak for all potential AQR users, but I’m willing to endure a little more friction/uncertainty when I need AQR assistance to avoid the new system being completely overwhelmed by people who don’t need it but would like to have it once they learn about it.
