"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."

"HotelCorporateCodes.com rates the Marriott DIS code as "Sometimes" for ID verification. No dedicated forum thread found specifically discussing Disney corporate code verification incidents. Disney has 140,000+ US employees and the code is widely circulated. One FlyerTalk user noted that a retired employee who disclosed their retired status was never asked for ID, suggesting properties prioritize rate code volume over strict verification. FL Marriott properties near Orlando HQ are most familiar with the code."

"Deutsche Bahn's Marriott code 11353 is a German railway operator code in the global GDS system. Outside Germany, this code is essentially unknown to hotel front desk staff. German Marriott properties near Deutsche Bahn offices may be more familiar, but the code is rarely discussed in English-language travel forums. No verification incidents found. European public transit company codes attract minimal scrutiny."
