"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."
