We are heading to Disney April 16-21. Contemporary is our preferred resort, so I've been stalking AP discount rooms there for our dates. I noticed that I can get an AP discount if I book for Tuesday, April 16 through Monday, April 22. But if I search for Tuesday, April 16 through Sunday, April 21 (our actual trip dates), the AP discount rate doesn't show up (well, it shows up, but only for more expensive room types). Can I book a room for April 16-22 and then cancel the last night and keep the same rate? Or will the rate change when I modify the reservation to take off the last night? Thanks to anyone whose had experience with this!
