I don't understand. A
DVC owner could rent to you at 11 months out. They would not have to wait until 7 months out.
Whether you rent from an agency (who acts as middle man and finds you an owner) or from an individual owner, the person must have a Beach Club contract in order to make a Beach Club reservation between 7 and 11 months out.
Whether you rent from an agency or from an individual owner, it can be someone who has a contract at any resort to make a Beach Club reservation at less than 7 months out.
Or maybe you know all this and I just didn't read your post correctly.
