I received an email a couple of days ago stating this:
If this were a Cat 1-5 cert it might be worth it.
Are they still offering nights credit? I've already received one night credit for my Marriott spending.
From February 1 through March 31, 2012, spend $1,500 a month for two months and get A FREE NIGHT E-CERTIFICATE at any category 1-4 hotel.* E-Certificates must be redeemed within 6 months of the issue date. Every time you use your Marriott Rewards® Credit Card, you're closer to a special free night stay.
