"Shell's Marriott code SHL appears in FlyerTalk corporate code compilations. Shell is a global energy giant with major US presence in Houston TX. Marriott properties near Houston Energy Corridor routinely handle Shell employees. No specific verification-denial cases were found. The energy sector code pattern tends to be less targeted than tech company codes in current enforcement discussions."

"I've been given codes for several chains from family/friends who are entitled to have them. All have assured me they have never been asked to provide company ID when checking in. In fact I was told they give the codes out to visiting clients who won't have ID anyway."

"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."
