Shel...don't depend on that! I only say that because I just tried to book a room at POFQ thru Travelocity that WDW said wasn't available..but Travelocity did.....
Well...I went thru the whole booking..listed my credit card, hit the RESERVE ROOM button and the screen came up saying that there were no availabilities...or something like that! I must have tried it 10 times, using different cards and everything....
Finally I called Travelocity and they told me that many times their screen might show availabilities when first searching, when in fact there are NONE!!
Plus, if you read the fine print on those sites..you will see that Expedia and Travelocity will not charge your card...that Disney will...which leads me to believe that it all goes thru Disney anyway....
Usually with those Travel sites, they charge your card immediately.
But, good luck...I know how frustrating it is.....I finally did get my room thru WDW...they ALWAYS have cancellations!!!
I hope I helped and didn't discourage you...I have gotten so much great help here...and I am very very new to the boards!!
