"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 wanted a higher room floor at a Seattle area hotel. I requested it at the front desk when checking in. The front desk thanked me for being a platinum member and told me that the hotel is fully booked and no “upgrades” to a higher floor for me. The girl behind me checked in and she was thanked for being gold, and they gave her a free upgrade to a suite and let her choose which room she wanted! I asked about the upgrade and they told me it’s random. I spoke to the manager and the manager said lots of rooms available and she gave me 5 rooms to choose from. 🤷🏻‍♂️ In the end, I got my upgrade. Had to fight for it."

"I don't do mobile check-in if I'm wanting to upgrade. I check the app before I go in to see if any suites are available to book during the duration of my stay. If there is I just say "Would it be possible to get upgraded to an available suite with my platinum benefit?". Of course this is typically at the hotel that I stay in about once a month for 3 day at a time for work. The front desk pretty much knows me and know that I am fairly low maintenance."
