If a FastPass+ reservation is made in a timeframe that is dependent on a resort reservation, and that resort reservation is cancelled, so is the FastPass+.
Some guests have been abusing the system by making a resort reservation, then making FastPass+ reservations using the resort guest 60 day pre-arrival window, and then cancelling the resort reservation. This will no longer be possible.
If you do have FastPass+ selections that are dependent on a resort reservation and you cancel, you will have a 2 day grace period to create another booking to retain those FastPass+ selections.
Another change effective this week limits resort hotel guests using the 60 day pre arrival booking window to a FastPass+ period as long as their resort stay. If you have a ticket longer than your resort stay, you will need to wait until the 30 day pre arrival booking window to make additional FastPass+ reservations. With a 14 day ticket being the longest available and using a 60 day pre arrival booking window, this puts the maximum FastPass+ window at 74 days.
