"Enforcement is highly fragmented across brand tiers. At Holiday Inn / Holiday Inn Express: minimal enforcement. At InterContinental and Kimpton: almost always verify. One user stated: "Airport Holiday Inns rarely check credentials, while InterContinentals in major cities almost always do." Properties near Seattle headquarters offer deeper discounts but face stricter verification."

"The only legitimate reason the hotel needs is that the company is giving permission, for whatever reason, for that individual to stay on the corporate rate. Since my uncle is THE guy to ask permission from, I see that to be a perfectly legitimate reason, and the paperwork (that so far has never actually been produced) would not be fake."

"FedEx's main IHG code (109207) is documented in the FlyerTalk IHG Rate Codes master thread. The IHG enforcement pattern for FedEx: "Airport Holiday Inns rarely check credentials; InterContinentals in major cities almost always do." FedEx monitors hotel usage volume with IHG — anomalous usage in one business unit could trigger company-side audit. One FlyerTalk user documented IHG refusing to honor a rate without ID and offering to cancel after the cancellation deadline. FedEx employee IDs are physical company badges recognizable to hotel staff."
