"Stanford University's Marriott code 349097 is an academic institutional code. University codes at Marriott select-service and full-service properties are rarely scrutinized. Stanford's Silicon Valley presence means nearby Marriott properties are familiar with the code, but academic corporate rates are not high-value enough to trigger enforcement. No verification-denial cases documented in any public forum."

"GAP Inc's Marriott code GAP is listed in corporate code databases. No verification incidents documented in FlyerTalk or Reddit discussions. Clothing retail corporate codes at Marriott receive minimal attention from front desk staff — retail employee IDs are not standardized enough to be reliably verified. US domestic properties rarely verify retail-sector codes."

"I have never been asked and I have 51 nights in a Marriott this year using our corp rate."
