Lisa3,
I'm sorry that they wouldn't let you stay another night, but from what I've heard (and I experienced this same problem at the All-Star Sports, and was told all 3 all-stars were booked, plus a lot of the other resorts as well, which was hard to believe for a fall date that didn't have any events going on that day), Disney blocks certain numbers of rooms for certain lengths of stay. Like, for example, if you'd said you wanted to stay 2 or 3 nights longer, the response might have been different, because of the way their computer reservation system works. One way to get around this seems to be to call up CRO from your room, and request a longer length of stay than what you really want (like if you want to stay 1 more night, request 3 or 4 nights more). Then if they say it's available, make the reservation. Then call back later and cancel the days you don't need. I know, it seems like you're lying to Disney, but in a way, they're lying to you, because in most cases, there really are some empty rooms for that night, but they're just saving them for longer length of stay guests. Also, if you deal with CRO instead of the front desk, they'll be able to give you the AP rate or Disney Club rate (if available), since technically you'd be making a reservation "prior to arrival" which is what those rates require.
