Yes, you can book a room with the AP discount. You would have to call to make the reservation, though, because you won't have access to the AP discounts on the website until after you get your AP.If I don't currently have an AP but plan to upgrade my 7-day hopper when I arrive, can I get the AP discount on a resort reservation now?
You'd think after all these years of going to WDW and having had an AP many times.. I should know this! haha!!!
We did the same thing last year. We stayed at WL and they upgraded our park hopper tickets to AP at the front desk when we checked in. We used to have to go to the guest relations at a park entrance so that saved a lot of time.
