There is a current promotion where you make 10 purchases each month (July, Aug, Sept) on your Marriott Rewards credit card and earn 1 free night in a Category 1-4 hotel. The E-certificate will be automatically deposited into your account. Valid for 6 months from issue date. And, there doesn't seem to be any minimum purchase amount... so go buy 10 packs of gum each month and pay separately!!! LOL!!! You apparently don't need to register for this promotion.
The return address on the card that I received in the mail is: Chase PO Box 17198 Wilmington, DE 19850-7198 It has a picture of the Eden Roc Ren Miami Beach on the cover. There is a code above my name and address, and again in small print on the inside: 901107975*14875-25 Or.... maybe I'm just special! LOL!!!!
