Nope, I disagree with *your* logic.
The 11-month window only lasts for one month -- then it becomes only a 10-month window, and is reduced each subsequent month. The longer you wait to make your reservation, the more likely it is that the rooms at a particular resort will fill up. There aren't enough rooms at any one resort to accommodate all the members who own there at one time, are there? Of course not. So obviously, the earlier you call, the better your odds are of getting what you want. The longer you wait (even within the 11-7 month window), the more likely it is that someone else will have reserved the room you want.
