"IHG corporate codes vary by brand. Airport Holiday Inns rarely check credentials, while InterContinentals in major cities almost always do. The likelihood of a request for ID is based on the size of the discount — the greater the discount, the more diligent the front desk. Be prepared to be asked for company ID if the discount rate is more than the standard 15% given to most corporates, or if the company rate is a fixed rate lower than the hotel's ADR. Cisco's IHG code (954410926) sits alongside IBM and Dell in the widely-circulated FlyerTalk master list; tech-company codes at this tier typically yield 10-25% savings and trigger occasional verification at full-service properties but rarely at Holiday Inn Express tier."

"Only once was I asked, by a new room (revenue) manager of a hotel I've used extensively. Explained that the code was provided by my contact at the company, offered to provide his information, and that contractors were included and allowed to use the code. Never had a problem."

"I had the same experience with the IBM corporate rate. When I went to IBM sites to install machines they always said stay at one of these hotels and tell them you need the IBM rate. Always worked and saved a lot of money and I always got full credit with the hotels frequent stay program."
