Hi, Michelle!
I love that you are planning ahead for your next Walt Disney World vacation! My family loves to plan for what resorts we want to stay at next!
If you book your 2013 vacation now, you can reserve your room but the rates will not be guaranteed until the official 2013 rates are posted (usually mid/late summer.) I have only done this if I want a very specific room during a busy time period and I want to make sure I don't miss out (for example, a Tower Room at Contemporary with Magic Kingdom view during spring break.) Remember, too, that to book for arrivals after December 31, 2012, you will have to do so by phone at (407)W-DISNEY.
If at any time you book a "room only" reservation and later decide to add on your dining/tickets, this must be done at least 48 hours prior to arrival so the system has time to process your change. If you are wanting a
special offer, watch the booking dates/availability dates as you will need to follow all the terms and conditions of whatever offer you choose.
I hope this information helps! If you need to know more, just
let me know! Have fun planning your magical 2013 vacation!
