Traveler Reports

"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."

"Just FYI, the Hyatt Regency Kiev does require Corporate ID upon check-in. My corporate rate is 220 EUR instead of 410 per night and they were quite insistent on getting the corporate ID. Good thing I had it with me."

"I was asking who was eligible to use OUR corporate discount when the GM volunteered this information. Management is way more visible at the (rather small) PHT than at larger Hyatts. I know I'm highly likely to run into the GM or his chief assistant during every stay, especially since I'm usually there for at least a week. Hence, I often hang on to my non-urgent questions until I see them. Might as well hear it from the source!"
