Marriott MegaBonus registration is open today through October 31. Last week I reported the four month Marriott Rewards MegaBonus offer is stay 2 times from Sep 15, 2010 through Jan 15, 2011, pay with Visa and earn a free category 1 to 4 reward night. A maximum of two free nights may be earned during this promotion. Free nights must be redeemed by May 31, 2011.
The reports on FlyerTalk indicate most people are getting the free night offer, although at least one member indicates a points-based offer for 25,000 points after 15 nights or a total of 40,000 points after 20 nights paid with Visa.
