"FlyerTalk's dedicated thread "AAA card – Do hotels check?" documents: "One frequent traveler staying 1-3 hotels per week was asked for the AAA card at about 10-15% of hotels." Another reported being asked only twice in 70-80 stays. The IHG/AAA discount is officially listed on IHG's website as a membership benefit — unlike corporate codes, this is a publicly advertised member rate. AAA rates are typically only 5-15% off, reducing hotels' incentive to verify."

"Dell's IHG code (954284898) is listed in the FlyerTalk IHG Rate Codes master thread but community members have noted: "the codes are generally not giving any significant discount — maybe 6 to 10% at the most. In some cases, the corporate rate essentially just gives you a refundable rate at the same price as the non-refundable rate." Low discount spread means low enforcement motivation. The practical consensus is that a sub-10% discount at Holiday Inn / Crowne Plaza tier rarely triggers ID requests. Risk rises at InterContinental properties, but overall Dell's IHG code is among the lower-risk corporate codes given the minimal discount depth."

"That being said, I've never been asked to provide any proof. It's not something I just do all the time, but I've never had any problems when I have."
