For those of you who are being told that there is no availability for the resorts you want, KEEP TRYING.
I called this evening for a standard room at Pop and was told with the code, all that was available was preferred. I said how about Movies, and again, only preferred available. She said standards were available at Music and Sports, but I really wanted Pop, and I really wanted the standard room, not the preferred, so I was very disappointed, and wasn't really sure WHAT to do as I hadn't anticipated any problems with this as my trip is in early December and I know that's a low crowd time of year. I told her I'd need to think about what to do and call back.
Someone mentioned the website code -- I went online after getting off the phone to compare some prices, and found the ZAW code listed on the main page at Disney's site. I tried to book with this code and it said the code was no longer valid (although it had said good through 9/30 and I was just on Disney's website yesterday and this code wasn't there then!)
So I thought perhaps with ZAW there would be a standard room at Pop available, and maybe it was an error on the website that said it was no longer valid, so I called Disney back and asked about the ZAW code, and the guy I got looked it up and said it was an internet only code so I couldn't book with that on the phone, but that it's the exact same discount as the ZBG code. I told him how I'd tried to book with it and the website said it was no longer valid, and he did say he'd heard they were having some problems with the website today so that could be what's going on.
So then without telling him what the girl ten minutes earlier had told me, I said I wanted standard room at Pop and gave him my dates, and he came up with it right away, no problem.
So I got my standard at Pop after all, and with the code, when I subtracted the cost of our tickets, it came to only 62.50 a night AFTER taxes!
So if you're being told no availability for what you want on the code, I don't know if they're lying to try to get you to book something more expensive, or if they're just mistaken, or if people are changing their ressies around so much that in that ten minute time period, a standard really did just become available, but you might want to keep trying, as it paid off for me!
