And when your FPs disappear, it means your plans have been “migrated” over.
And then, because of reduced park capacity, either they eliminate FPs altogether or they reset the FP system to be the 4th FP of the day. So that you book one at a time, on the day. And they control availability to be more like boarding groups. My guess is numbers are low enough to not need FPs.
Just my thoughts
The one big question is, is there enough capacity in the parks to do that? But it does sound like it, from Chapek’s comments.
