I made a reservation for next January in Hawaii and have a Category 5 certificate. However, that hotel went up to a category 6. So, I reserved the hotel when it was a category 5, but want to attach a 7-night category 5 certificate. Marriott even said that if you book before March you lock in the amount of points you need.
What should I be asking Marriott when I call in? This should be possible, right?
