"Facebook/Meta's Marriott code FSF is one of the more recently discussed tech giant codes. FlyerTalk tech-company code thread: "Meta's corporate rate delivers solid discounts in the Bay Area." Properties near Meta HQ in Menlo Park/Palo Alto are most likely to see genuine Meta employees and to verify. Meta's standard corporate ID is a photo badge with company logo — easily recognizable by hotel staff in Silicon Valley. Hotels farther from Meta's campus presence: minimal verification. Post-2022, Bay Area Marriott full-service properties (W Hotel SF, San Jose Marriott) have increased scrutiny of tech company codes."

"I have been asked to show some proof couple of times. I normally show my corp id but credit card with employers name on it has worked, too. As would probably just showing my laptop with employer e-mail account or whatever. My impression has been they are happy with just about anything that proves I'm working for the company whose rate I use and why wouldn't they."

"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."
