"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 stayed 100s of times with various corporate rates (including Japan) and the only hotel that has asked is W hotels. Even then they didn’t push much. I have been a consultant for 20 years and many clients require you to use their rates when they are paying the bill. The hotel doesn’t have an up to date list of every employee that works for a company globally. The woman at the W said “I don’t really care, just show me anything on your phone that says your name and that company. You can type an email now “."

"I wouldn’t mind that at all. Credit Card companies have super weak security and it’s very easy to defraud them - they just pay our money back, and counts that as losses so we’ll sure up about it and keep using the cards What I mind is that the mobile check-in is basically a lie. Marriott is deceiving me. Random hypothetical people that might or might not stole my credit card are not. Hilton works just fine btw"
