"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 am very rarely asked to prove my eligibility for a rate...but they have every right to ask and if you can't produce it, you will be re-rated to the current rate, which is often even higher and there is no guarantee points rooms will be available. Doing online check in rarely helps this as most properties don't actually do online anyway - especially to people who are not returning guests to the property or elite. You are taking a gamble. One that is likely to be fine. But understand you are intentionally breaking the terms of the bonvoy program and if someone really cared, there can be consequences."

"I work front desk and it seems like management is really pushing to check IDs for any special rate. Personally im lazy and also don’t care that much to start a confrontation so I only verify govt rates and employee rates, but yes it is being enforced more harshly. Corporate rates I guess are easy to find online and thus abused. Again, I don’t care that much because they’re still pricey anyway !!"
