The AP discount, if available, varies seasonally. So sometimes it will be less, sometimes more, than the
DVC discount. The best thing to do is just call and check availability.
Remember though, if you are mixing cash nights and points nights, the CRO reservations currently aren't linked with DVC reservations. There is a possibility you'll have to move. And you will have to check Pu and back in at the front desk, even if you don't have to move.
