"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."

"I have a reservation in DC this weekend (11/14) and the LTO110 code showed up for it when I rechecked availability/rates. A call to GP customer service verified the rate and dropped the price 10% below what I'd previously booked. It does require a bit of clicking about on the site, but it's there. Under 'reservations', hit 'specials & packages', then the 'hyatt special offers' tab. The link to the LTO110 rate is the fourth one down."
