If a particular hotel is busy because of a high summer season, for example, award nights at the property may cost up to 33% more. Similarly, if a conference in town is soaking up open rooms, award prices will also go up.

On the other side of that curve, when demand is low, award prices will go down by a similar amount. Marriott has promised that for every room that sees an increase in price because of demand, another will be discounted.

What the new pricing algorithm creates, in effect, is a way for Marriott to better manage the way it gives away award nights during times of the year in which demand is high.
