"Oracle's Hilton corporate code is widely circulated on public code-sharing sites. UK and Asia-Pacific Hilton properties have introduced systematic ID checks. Oracle being a high-profile tech employer near numerous Hilton properties (San Jose, Austin, London) means front desk staff are more likely to recognize Oracle employee IDs and actively request them."

"I would contact your corporate travel. I know some companies have one code for employee business travel and one for employees and their families. Some use just one for all. Shouldn't be too difficult to email to your travel team to get clarification."

"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."
