"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 used to work night audit at a 4 diamond Marriott resort. It was me, an 80 year old valet who just slept in the cars, and a 4'11" security guard. She wouldn't check anything out because "I'm a woman. If there's someone there, they could attack me." So I, the 19 year old woman, would investigate. Guest needed towels? I brought them. I would have to go up to a computer room to run some of my reports. I occasionally had to pee, because I'm selfish like that. So whenever I was gone from the front desk, it was just unstaffed. It sucked."
