I received the card early last year. I also had 5 stays last year and so earned premier by stay activity by virtue of the card. My certificates (both my President's Club and my free night visa cert) have posted, and it does not appear that I have received a gold upgrade cert.
I had posted above a question whether a cardholder making premier on stays would receive the gold cert the next year. The T&C were not particularly clear. While it may still post in the future, it appears the answer is no, in my case. If it hasn't posted by the end of March, I may contact Fairmont.
