Earlier today I called to ask about the club floor upgrade and they were able to give it to me using the credit card I have on file (which is my Chase Marriott Visa and not my RC card). I also couldn't see the T&C on my cert, just that I had 3 of them.
I'm guessing since they are both from Chase and Marriott/RC cards it is ok, but reading the above will remember to take my RC card with me just in case.
