"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."

"I have used my corporate code multiple times and never once have I been asked for an ID."

"So - to the point - how do I verify my entitlement to this rate? The concept of showing a 'Government ID' is frankly outdated in the UK - aside from the NHS, I don't imagine there are many (any?) government departments (aside perhaps from the military) that have a great big logo/badge advertising that you are infact working with the Government - this is in itself a significant security risk."
