"Morgan Stanley's Marriott code MOS is listed alongside Goldman Sachs and UBS codes in FlyerTalk's compilation of financial institution corporate codes. The SF Marriott and midtown Manhattan Marriotts were specifically cited in enforcement threads as properties that "cracked down on corporate code abuse." For financial sector codes, the discount threshold triggers audit flags — if Morgan Stanley's rate is 20%+ below BAR, full-service properties are more likely to verify. US domestic verification: 10-20% at urban full-service; Europe/Asia: meaningfully higher. No MOS-specific denial incident documented."

"I mean, it depends on the size of the hotel. Having one person on night shift for a Fairfield isn’t uncommon. The better hotels have more people working at front desk even at night simply due to the size and brand. I’d however say though, if the property has been notified of the guest’s check in time in advance, and part of deal of getting into night shift is to check people in at unusual hours like that, then it certainly does not sound right to me that the front desk agent cannot have the meal earlier or later out of that many hours of the shift."

"I always see people saying that they aren’t able to do mobile check in. I’ve only stayed at two Marriott hotels where I tried to do mobile check in ( both of them never been to before) and they both let me without having to go to the front desk which I was really happy about because I had lost my ID and didn’t know how I was going to check in. Also I think I only had about 20 nights at the time, I usually stay with my boyfriend because he’s titanium."
