"HP (alt) Marriott code 5105 is a secondary HP/HPE code, alongside the primary HPQ code and alt code 5444. HP's primary Marriott code HPQ is one of the most widely shared codes in FlyerTalk's publicly usable Marriott codes thread. The same risk profile applies to alt codes: Marriott's automated system has been documented to disable Mobile Key for high-risk codes, forcing front desk interaction. HP-heavy markets (Palo Alto, Houston TX) have heightened verification. No 5105-specific denial 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 think the generic 'show corp id' designation means show the company business card. I think a lot of us don't have them or, if we do & we're not going to an office that we'd need to show them, leave them at home. I worked for some F500s that didn't require corp ids with shiny smiling faces on them & others that did; same with company credit cards. All, however, provided biz cards when working for them."
