"T. Rowe Price's Marriott code TR5 is a financial services code. T. Rowe Price is headquartered in Baltimore MD. Financial sector codes at Marriott receive moderate scrutiny. FlyerTalk's finance code enforcement thread: "Finance codes in NYC/SF are most scrutinized; Baltimore/suburban markets have lower enforcement." hotelcorporatecodes.com lists finance codes at "⚠️ Sometimes." No TR5-specific denial documented. Baltimore-area Marriott properties near T. Rowe Price HQ are most likely to encounter genuine TRP employees."

"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."

"I now always make it a matter of course to carry documents (business cards of my contacts, e-mails requesting my visit etc.) from my host company when I travel. This has always proven sufficient for the few times I've been challenged by the front desk clerk."
