"Sony's Marriott codes (SON and 12698) appear in FlyerTalk's Marriott corporate code compilations. Sony has major US presence in New York (Sony Pictures, Sony Music, Sony Electronics) and several Marriott full-service properties near those offices. hotelcorporatecodes.com lists SON as "⚠️ Sometimes" with 10-15% discount. Japanese multinational codes tend to face higher scrutiny at international properties. No specific SON denial documented in FlyerTalk. Properties near Sony's Culver City (entertainment) and Park Ridge NJ (electronics) offices carry higher verification risk."

"I work as a consultant and frequently ask for and use my client's rates (at their insistence, since I will be billing them back). I have been asked for ID maybe one time in 15 since February, when it was announced in this forum that rates would be ID'ed."

"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."
