Just a thought...are you a Delta SkyMiles member? If so, and have some miles accumulated, you can reserve a hotel room either totally on miles or with a combo of miles and cash (seems fairly discounted) through the SkyMiles Marketplace. I've been checking rates for 2 nights for our June trip and they're pretty good. I can get 2 nights at the Swan for 33,000+ SkyMiles.
I've seen the Hyatt Airport on there as an available hotel for our dates. May not be available for your date(s) but you may just be able to snag it with a few miles and some cash.
Not a bad deal if you've got SkyMiles that are just sitting there as we do. (We haven't flown Delta in years).
