"One FlyerTalk user reported using the IBM corporate code for 14 years, 80–100+ nights a year, and never once being asked for ID. However, Newark Airport Marriott religiously asks for ID, requiring a letter from IBM stating you are a legitimate contractor. Consultants who tried to use a former employer's IBM code and couldn't produce valid ID were charged the full going rate of ~$300 instead of the corporate rate of ~$100."

"I work for the front desk, at a Marriott, & have for the last 8 years .... So when it comes to room upgrades; it goes based on AVAILABILITY... sometimes no matter the tier, if we have it available - I will upgrade the guest. Now of course, higher tiered members get dibs on the upgrades first but after we go through the higher tiered members, Ambassador, Titanium, Platinum - then we go through the other ones. I cannot express this enough : BEING NICE & POLITE AT THE DESK GOES A LONG WA"

"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."
