旅行者レポート（原文は英語 / Original reports in English）
Data refreshed today
"The AON Hyatt code delivers unusually deep discounts at certain European properties, notably Paris. Hyatt is known as more verification-active than Marriott: "Hyatt is notorious for checking for ID and being quite thorough." Park Hyatt properties explicitly state "Valid Company ID Required at Check-in." One verified traveler reported Park Hyatt Tokyo demanding proof or threatening rack rate conversion, taking 15 minutes of email-searching to satisfy. For AON specifically, no denied-rate incident was found, but Hyatt's general enforcement rate is estimated at 10-20% of stays."

"We just have to book under our corporate rate in Concur regardless of rate. Example in Columbus, OH our 2 preferred properties are Hilton downtown and Hilton Polaris those rooms can be $400+ a night. If I book at the Hyatt House at $199-$225 also part of our general corporate rate off BAR it will tell me I’m out of compliance for not booking our preferred hotels even though they are more. I override this all the time but that’s how it works."

"I use corporate codes all the time and never get asked. I shouldn’t be using them but, hey, it is what it is. The risk is you get that front desk agent (or even manager) who goes “I see your with the Coca-Cola rate, can I have your corporate Id please”? Has never happened to me yet but it is a risk. So book accordingly."
