Dumb question@:-)... my apologies.

Booked a 7 night stay with a rack rate... wanted to make sure the dates I needed didn't sell out. I should however prior to arrival have enough pts by then to cover my entire stay... am I able to switch my stay over to pts before I arrive or do I have to make a new booking and hope the dates I want are still available.... I'm not bothered if the use of pts are through the saver option or not.

Thanks in advance !
