I just booked a five night stay using points and was charged for all five nights? How does the fifth night free work? Do you have to book somewhere other than Marriott.com, selecting the "use points" option? Also I was surprised that I was surprised to see that I was being booked in what appeared to be the worst room in the hotel, with an option to PAY for an upgrade. You would think being a premium member I would be treated to the best room available. If not for anything else but word of mouth.
