A great Promotion, I think I and my wife will make at least 20 free nights before promotion ends.
AAA Rate can knock down the room rate significantly and earn credits
P.S, If you enroll in Hyatt after I mentioned here, but before today, your will get 2 free nights after 2 stays. It is too late now.
