The most significant issue affecting Marriott Rewards members when the hotel reward category reassignments happen on March 15, 2012 is the set of hotels moving from Category 4 to Category 5 that will no longer be available for reward nights with the free night certificates earned in the past two Marriott MegaBonus promotions.
The free night certificates received for MegaBonus and the enrollment free night certificate for Marriott Visa cardmembers are limited to category 1-4 hotels. Nearly 100 hotels are rising from category 4 to category 5 and will not be available for reward nights using these certificates after March 15.
Marriott Rewards members sitting on reward night certificates may want to closely examine the list of hotels in this post rising from category 4 to category 5 on March 15, 2012 and decide to redeem certificates for hotel stays prior to March 15. You can book a stay using the certificate for dates past March 15 as long as you make the reservation before the hotel rises to category 5.
Marriott Visa Premier cardmembers receive a certificate good for category 5 hotels with renewal membership. Check out this list of category 5 hotels moving to category 6 to see if there may be a current category 5 property to book your reward night before the hotel rises to category 6 on March 15.
