Club Marquis (in some form) stuck around once Marriott Rewards began. I remember the one (and only) time I hit Marquis Black level, it was in '99. I have my card here which shows "Marriott Rewards" with the black "Club Marquis" banner on the right side - expiring in 11/00. I'm also pretty sure that I do remember earning that status only via Marriott stays (not CY) - but I could be wrong on that point. I just remember that I was trying my darndest to find regular Marriotts just so I could get that! I have a regular Marriott Rewards gold card expiring in 01/01, so my guess is that the "Club Marquis" name went away sometime in 2000.
