We will be trying to book a Disney Cruise tomorrow for 2011 using our points. (Please NO debate over points vs cash, we have all ready looked at that, and the only way we will be able to do the cruise is by using points.) But what else do I need to know? For those who have done this before, what surprises did you encounter? What tips would you give? (This will be our first cruise ever, let alone Disney.) Any and all advice would be appreciated. TIA.
