Marriott Bonvoy membership and its benefits are offered at the discretion of Marriott. Marriott and its travel partners have the right, without limitation, to change, limit, modify or cancel Program Rules, regulations, rewards, and reward levels at any time, with or without notice, even though such changes may affect the value of points or miles already accumulated, the ability to use accumulated points or miles, or the ability to obtain certain rewards. Marriott and its travel partners may, among other things:
increase or decrease the number of points or miles received for a stay or required for a reward;
withdraw, limit, modify, or cancel any reward;
add blackout dates, limit rooms available for reward redemption at any participating hotel, change or restrict participating hotels, or otherwise restrict the continued availability of rewards;
change program benefits, travel partners, locations served by Marriott or its travel partners, conditions of participation, rules for earning, redeeming, retaining, or forfeiting points or miles, or rules governing the use of rewards;
change or cancel its travel partner rewards. The accumulation of points or miles does not entitle members to any vested rights with respect to points, miles, rewards, or program benefits. In accumulating points or miles, members may not rely upon the continued availability of any reward or reward level.
