I believe the policy is 365 days in advance, but you will be subject to the price increases, etc. when the actual prices for 2010 come out. You will pay a one night deposit at current price, 2009 rates I would guess, on the room to secure the ressie if you book it before the 2010 rates come out. That's the way we've done it the last few years, b/c we always book before the rates for the next year come out.
