"ThyssenKrupp's Marriott code TSN is for the German industrial conglomerate (steel, elevators, automotive). German industrial codes follow the European Marriott enforcement pattern: "In Europe, they tend to follow the rule by the book." ThyssenKrupp has significant European properties in Essen/Duisburg (HQ) and US operations in Birmingham AL, Pittsburgh PA, and Calvert AL (steel facilities). FlyerTalk notes German Marriott properties are among the most verification-active. No TSN-specific denial documented."

"I have a close friend who is a GM at a Marriott property in a fairly large US city (top 25 metro population). Their opinion is basically, "Hey, it's business. I'm not turning away a paying guest if they don't have the right ID." In this person's younger days as a front desk agent, they enjoyed catching people trying to use a corporate rate that the guest was not entitled to. As they became higher up and saw the books, occupancy rates, etc... Corp ID's became far less important than filling rooms."

"I mean, when I worked night audit, the whole night is practically a break after like 1am. It was usually just me and one other guy running the place (the other guy is just cleaning and doesn’t know how to do front desk). We don’t get an actual “lunch break” where we have to clock out for 30 minutes because we can’t leave the desk completely unoccupied (unless you were going to the bathroom or tension to a guest away from the desk or something). And we just ate at our desks if we were hungry, not sitting in the back."
