"hotelcorporatecodes.com flags CapGemini N0990552 as "Sometimes" ID check required. Consulting-sector codes cluster in the "Sometimes" tier because the per-night discount is meaningful enough for high-demand properties to query it. The FlyerTalk London thread (November 2023) documented that UK Hilton properties have broadly moved to requesting corporate ID on discounted codes, which directly affects large consulting firms with London footprints like Capgemini."

"My spouse and I usually use his corporate leisure rate for reservations at Hiltons around the world and we have never once been asked for evidence of working for that employer, even when the reservations are in my name."

"I called the hotel and spoke with someone who was adamant that I had booked a Government On Business rate and would need to show Government ID. I explained that there was a difference between having access to a Corp code which allowed access to HM UK Government rates (which I have done regularly for 15 years) and booking an OnBusiness Government rate directly by clicking the box on Hilton.com (which I have never done). She wasn't moving and insisted this was the same thing."
