"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 have used heavily discounted corporate rates for many years all over London, and have not yet been asked for ID. If I was, all I could do would be to send an email from my work account which at least is clearly from the associated company."
