"MIT's Marriott code 363006 is a university institutional code. No FlyerTalk thread discusses MIT verification incidents. University codes at Marriott are used primarily for conference and research travel — a use pattern hotels accommodate with minimal scrutiny. MIT has strong presence near Boston (Kendall Square), where Marriott properties are plentiful and familiar with academic corporate rates. No verification-denial case documented. University codes are among the lowest-enforcement categories across all major hotel brands."

"It’s about 80/20 for me. 80% of the time I still have to go to the front desk. I’ve asked the front desk folks, and they always say “our property has a policy to not allow mobile check-in”… I guess Marriott allows this at the property’s discretion. One property said they don’t want the guest to get stuck with full charges if they end up having travel issues and mobile checked-in the day before."

"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)"
