Me neither. At best, a small meeting room maybe holding 12 people max. BTW, the Marriott (and other hotel chains) have so many different room rates, codes and "deals" that I doubt the disinterested FD clerk at the Front Desk is going to bat an eye or care about what rate your rate is pre-loaded in the computer. Maybe at a FS or higher it might get a glance. Below that, don't think so. Just my opinion. What's the worst that can happen, charging you a higher rate?
