"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."

"Bank One's Marriott code BOB may still exist in Marriott's GDS system following the 2004 acquisition by JPMorgan Chase. JPMorgan has a separate Marriott code (JPM). Legacy acquired-company codes are practically never verified as the hotel has no way to confirm employer identity for a company that no longer exists independently. Risk for legacy codes is negligible."

"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)"
