"GE (alt) Marriott code 9360 is a secondary General Electric Marriott code. GE's primary Marriott code pattern is Medium risk — FlyerTalk documented GE as one of the companies that monitors internal employee use of hotel corporate codes, with documented terminations for leisure misuse. Marriott properties in GE-heavy markets (Cincinnati, Boston, NYC) are familiar with GE employee IDs. No specific 9360 denial incident found; risk pattern mirrors the primary GE code."

"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 regularly stay at a renaissance once a month on our DTC rate and have done mobile check in but always end up at front desk. One time the front desk was like oh. We know you as you have been coming regularly, but I need to double check your id. I think it’s because someone shared it online and now it causes random checks for rest of us."
