Here's a copy of the current BB flyer posted by DISer "Rootskate" (thanks to Rootskate for posting it) so you can see what it looks like when you call and beg them to let you book it

Since you asked and no one knew about it while you were there and now you can't call the extension 8844 from the room, you might try the 407-541-5523 number on the flyer and explain what happened - and even though you are supposed to book prior to checkout, I have read other DISers posts here where they WERE allowed to book in this situation, so I hope it goes well for you too.
*EDITED TO ADD - not on the flyer shown, but when you call the extension 8844 from your room to book, you can also choose from these BB offers:
Get 40% off a Select Disney DELUXE Resort: 1/3-1/14, 1/18-2/11, 2/15-3/27, 4/11-7/1, 7/5-11/23, 11/28-12/24/2010
Get 45% off a Select Disney DELUXE VILLA Resort: 1/3-1/14, 1/18-2/11, 2/15-3/27, 4/11-7/1, 7/5-9/30/2010 (Offer excludes 3 bedroom grand villas).

Also to OP, I agree about probably not getting any 2011 dates on a BB this early. Usually you would see next years dates first during the
Free Dining period for the next years Free Dining dates, and then after that FD BB expires (usually October), the
next BB that starts showing up in rooms Oct/Nov will have some of the next years BB dates on it. Whew, hope that made sense.
JMO if you're looking for 2011 BB before that, I would probably book whatever BB is offered during your stay, then
try and modify that res when new BB dates show up here on the DIS (which I've also read of DISers doing). Hope you have good luck too!
