It's good you filled the survey out. You know, I'm in the top 50 guests at the Marriott RenCen in Detroit. I have been asking for a suite upgrade for the last 3 years almost every week. While I've never gotten the typical suite upgrade, I have gotten a nice gesture of upgrading me to a huge party room but I would love to get a regular suite. I guess it is luck of the draw. However, I can't believe you have not been able to get into the Club Level rooms. Is it the case that the rooms you get are actually upgraded rooms and you get Cong. Lounge access (thats what I get at my usual Detroit hotel). That might be the case and then they sell the rooms on the Con. Lounge level for a premium.
