"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 have a personal travel option in Concur and can also use the corporate travel agency for personal travel. Rates usually match between Concur and booking direct with the code but vary from time to time. The PH Sydney dates I looked at were $1,200 (BAR), $700 (corp code), $500 (Concur)."

"I mean, you can book the rate, but 100% PH Tokyo requires proof of employment. I had to email from corp domain and provide a business card (Dec 2022). If you show up and can't provide proof of employment, either you'll be paying a very expensive full price for your stay, or they'll invalidate your reservation."
