"AT&T is among the companies with the best Marriott negotiated rates. In the US, I've never been asked to show corporate ID. In Asia and Europe, I've been asked for corporate ID every single time. Since some companies don't put their name on badges for security reasons, the business card route is often tried first and usually accepted."

"lol, my front desk managers *hated* any time I asked them to cover AYS. They’d go out to the desk and help no problem, but I always got some kind of attitude asking them to hop on the phone for my break. I worked at a ~650 room property and was regularly scheduled by myself for AYS second shift."

"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."
