I agree with this about differentiating between AP holder non-resort guests and AP holder resort guests. They have to make sure AP holders who aren’t staying onsite don’t take up too many spots which preclude onsite guests from entering the parks. Why would you pay to stay at a WDW resort and not get into the parks?!?
I got the AP email this morning. It sounds like they don’t want AP holders just hanging onto too many days at a time. I’m sure if you have a resort reservation, you have a particular limit on the number of days you can hold during your trip. If you don’t have a resort reservation, then they set a different amount of days you can hold. They have to disclose this, since we, as AP holders, are supposed to be able to go to WDW any time we aren’t blocked out.
