The 2009 prices will be out sometime in August. You can book a room only now, which will be quoted at the 2008 peak or holiday rates, with a 1 night's deposit. Then the price will be adjusted when the 2009 prices are released. But if you want to book a package, you will have to wait until the prices come out. Also, if you are thinking of booking room only now and then changing to a package after the rates come out, you will need to cancel the room only and book your package, as you can't just add tickets and dining to a room only ressie to make it a package.
