"Intel (alt) Marriott code INL is a secondary Intel corporate code alongside the primary IBS code. The same low-enforcement pattern applies: Intel's IBS at 10-15% discount is in the low-pressure verification zone, and a secondary alt code is even less likely to be scrutinized. No INL-specific denial documented. Intel's Hillsboro OR HQ and campus cities (Hillsboro, Chandler AZ, Folsom CA) mean nearby properties handle Intel employees regularly but enforcement rates are low."

"I have never been asked (yet) at Marriott but usually I show up at the desk by handing over ID/credit card. Don't read this as me endorsing going crazy using the codes that you aren't supposed to use! Interesting about the client reports going back daily."

"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."
