I just checked and the promotion was on my page.
Stay 12 Nights at Marriott and Renew Your Marriott Rewards Elite Gold Status
Only the best will do for you. That's why we're giving you one of our very best offers: A Taste of Gold. Enjoy Marriott Rewards Elite Gold membership through July 31, 2009. And when you stay 12 nights or more at any Marriott between May 1 and July 31, 2009, you'll be upgraded to Elite Gold through February 2011. It's that easy to sample, and then earn, the Elite Gold rewards that you can enjoy at Marriott.
So, does that mean I am only gold until July 31 unless I stay the 12 nights between May1 and July 31. After my 7 night trip next week will only need about 7 more nights anyway to reach gold status.
