Starting in September, the program will move to a dynamic model that prices awards across three tiers as a function of demand. In the peak season or when a hotel is otherwise busy, members will pay 14–33 percent more for an award night. On the other hand, off-peak discounts in the equivalent amount will be applied when hotel traffic is light.

Marriott’s move comes in the midst of a global industry trend in which travel industry loyalty programs are moving toward dynamic pricing in selling award seats or nights.
