We purchased in May and I banked my points to 2003, thinking we would use them in 2003. Now, we are talking about possibly going in November if we could get in. Can I pull my banked points out and use them?
No, you can't. Once points are banked (or borrowed), they cannot be returned to their original use year.
The good news is that if you want to take that November trip, you can borrow some of your 2003 points to do it. Just be sure before you make the ressie that you will really go, because if you cancel that trip, you will have to use the borrowed points before the end of your 2002 use year or you will lose them.
