I think that's the same question I'm wondering about. Am just starting the resale process and wondering how far in advance of arrival date I can use points for a DLR hotel room (I realize that's not a "good" use of points, but it will work in my situation). Can the ressie be made when you have available points or does it relate to the 11 month, or 7 month window? Is there a cancellation process available like a regular hotel rez, or once you commit the points, they're committed for the DLR hotel room? (I won't have access to the member's site for awhile -- and I'm sure hoping it's better (more informative and easier to navigate) than the regular WDW site!).
