"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."

"I don‘t want to violate the T&C and risk my LTG status and account being closed….so I proactively contacted MHC and explained the situation.

Will be interesting to see what they come back with…"

"We may have an issue of semantics regarding the travelzoo code. Often when Travelzoo has a special rate for a Hyatt Hotel that rate is also shown in the "Special Offers" section for the particular hotel on the Hyatt Website. The code for the comparable "Special Offer" is 13147 which is often referred to as the Travelzoo code. As this code is available on the website, it gets both stay credit and points. At least, this is my impression."
