I was thinking that same thing. Unfortunately, the time I want to use my point for is the week after Thanksgiving. You better believe I'll be one of those early callers on May 16th!! If I can't get anything for November, I'll probably bank my '07 points and use them for our March trip combined with '08 points. We have a March use year.
I'll be calling to switch for a busy time, too - I will also bank my points if I am unsuccessful at booking for Dec 07.
