It depends on time of yr, which resort, room type, etc. We just booked VWL studio for Aug 24-29 and it was wide open at just under 5 mths. Check out the Availability thread to get an idea of the different resorts and room types 7 mths from now, which is a slow time.
I own my points at Old Key West and have made reservations at many different resorts. I assume you are looking for examples and I won't bore you with all of them but for July 4th, 2005 I was able to book three studios at the Beach Club resort.
