At this point, the requirement to make a park reservation is just nonsensical, and frankly, an annoyance to Disney's most loyal customers. We have a 2 week trip coming up. My daughter and I have APs, and the other 6 family members do not. Having to make reservations removes our ability (or at least makes it more difficult) to change plans on the fly. Why do we need a park reservation if we can immediately hop to another park after tapping into the first one? What purpose does it serve?
Sometimes you really have to wonder why Disney does some of the things they do. Please, someone in the know, make this make sense to me.
