"Qualcomm's Marriott code QUA is listed on AeroPenguin's Marriott code compilation. Qualcomm HQ in San Diego means properties there encounter genuine Qualcomm employees regularly. FlyerTalk's general Marriott tech-code enforcement: "Hotels within 5 miles of tech company HQ are significantly more likely to verify." Qualcomm has a smaller footprint than Intel or Cisco — less nationally recognized — so verification is primarily concentrated near San Diego. No specific QUA denial incident documented in public forums."

"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 occasionally try to get the corporate rate for a company I'm visiting in the area (for sales/consulting). Only once has a front desk clerk asked me to prove my eligibility, and she was satisfied by me giving the name and telephone number of the person I was visiting."
