"A user specifically asked about Accenture corporate rate code for international properties. Hilton's execution is stricter than Marriott's generally. The Accenture code circulates widely in consulting circles — with the same recognition level as Deloitte and McKinsey codes. Discount typically at 15–25%, placing it in the medium verification risk range."

"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."

"I run a Consultancy and work with clients across both Public and Private sectors. Many years ago (15?) a UK Government client (they are still an active client) shared a Hilton Corporate Code, which was to be used for stays required when working with them. This code gives access to (but not 'On Duty' rates). I use this code regularly across the UK (mainly London) without issue, staying most months at various London Hiltons."
