Ok, wait times are looking VERY reasonable at both parks, and they have not opened any more reservations for today that I've noticed as of 10:30am.
Tomorrow (Sunday, 8/29) is also currently completely sold out.
This suggests to me that they have a very restrictive AP cap at the present time. I have a friend at DCA raving about how empty it is and how they're just walking on rides. The app is showing everything but RSR at 20 minutes or less, with many 5-minute waits, and that's even with Toy Story down.
So, that's great from a low-crowd perspective. But if that's the situation with APs sold out, then that's not what I was expecting from an AP access perspective.
Now, who knows how they'll adjust any of that. It's still traditionally one of the most low-crowd times of the year, and they may have decided that they want to show it can be low crowds even WITH APs, since that is a topic that gets so much complaining... but I'm surprised that they're not allowing people with shiny new, expensive APs to visit if the parks are as empty as they look.
ETA: I guess it's only 10:30am, and I forget a lot of APs roll in later since that hasn't been a thing all year! So, maybe this could be a thing that happens where reservations are sold out but those rezzie holders don't materialize until later in the day. We'll see!
