With the introduction of peak pricing, these certificates are basically useless. Why say that they are good for up to a category if the points requirements would exceed them. It's not as if I can use 35K certificates plus 5,000 points from my account so I can use it. Canceling my credit cards (Ritz, Marriott ,Marriot Biz, Amex (all 3 as well). I was only keeping the cards for the certs but now no more. Marriott has gone downhill. I have been staying more at Hyatt and Hilton hotels.
