Hmmm... Sure would like to say don't be worried, but that is Labor Day weekend and considered by many to be the last opportunity to hit the beach for the summer. I wish you good luck. If you have the points you should walk it through, meaning reserve the full week before including your first day of your stay as the last day of the reservation, then call the next day and cancel the first day and add the next day, and so on. If you are successful cancel the remaining days you don't really want. I'm assuming this is still allowed.
Edit: Just realized you're mod w/43k posts. I'm probably not enlightening you to anything new.
