With this promotion and the 5,000 points after every 3 stays, you can come out pretty well this quarter. After 9 stays, for example, you can walk away with 16,200 Southwest Rapid Reward points (which can be redeemed for $270 in Southwest flights) and 15,000 Hyatt points (1 night stay at a Category 4 hotel). If you are short on earning status for this year, this could be a good opportunity to get some cheap mattress runs and recoup your spend with these bonus points.
Make sure to register for this promotion online or by calling 1-800-30-HYATT and providing promotion code WN02M. Also, from past experience earning miles over points with Hyatt, typically I would have to call Hyatt Gold Passport and ask them to change the earning preference to miles after the points posted to my Hyatt account. They will manually do this for you as they recognize some of the flaws in the system.
