Many people are also referring to the free night(s) one receives as a Marriott Visa holder, or the ones received as a part of a MegaBonus....if you have received any of these that are currently active, they will be found under thee "Unused Certificates" on the My Rewards Activity page of your MR account.

EEO's can also be found under "View Platinum Offers" in the Rewards Activity section of your account. New ones were just posted this week....

Be sure that you are registered to receive emails from Marriott, that they are not going to your SPAM folder....and that you are reading them when they arrive. We recently received an offer for a free CY night, and another for a SHS points bonus that (was enough to) redeem for a free night - all in addition to the current MegaBonus!
