"Harvard University's Marriott code 17885 is an academic institutional code. No FlyerTalk thread discusses Harvard verification incidents. University codes at Marriott receive the lowest enforcement treatment — hotel staff view academic institutional rates as similar to government rates in terms of legitimacy. Harvard's Cambridge MA presence means nearby Marriott properties (Marriott Boston Cambridge, Sheraton Commander) are familiar with Harvard employees. No verification incident documented."

"I can say, with absolute certainty, I've never been asked for a Corporate ID: only a business card. Despite working for a company towards the top of the F50 list, I am a remote employee. Remote employees are not given IDs in our company. When I do have to go to the office, I need to get a guest ID."

"I have been a Platinum for a few years (which implies I frequent Marriott properties on a regular basis) and up until tonight was NEVER asked for any id to justify a corporate rate or discount (I legitimately use a few corporate rates I am entitled to and AAA rates)"
