Your points are "normally" called "vacation points".
When you use vacation points to reserve something in the Disney Collection, the Adventurer's Collection or the Concierge Collection, the vacation points are converted into "reservation points". If you cancel the reservation within the deadline (which varies between options), the reservation points are still returned to your account. However, those points cannot be used to make a reservation at a
DVC resort or for a trade via II, and they expire at the end of your use year.
