I had this unit come up for a deal in express deals. Pretty sure it's the Hyatt but wanted other opinions. I looked on Hyatt's official site, and all the amentities match up, specifically the "pets allowed" which I didn't see at the Rennaisance or the Holiday Inn (if there's been some sort of sudden star rating change). There is also a Hilton down there too which usually shows up as a 4.5 star on most hotel sites as well, and it has a casino too.
