A Giant Shell of a hotel with an empty soul
I don't know if this hotel ever "worked" even when I remember it opened as a Doubletree Hotel 20 some years ago. It has a very modern exterior and palacial interior, but feels cold and without soul. The restaurant on site is a LA chain restaurant called The Daily Grill. It was dead when the hotel looked busy, and no wonder: Their buffet breakfast was $23.00! In comparison, I had the buffet breakfast at the Beverly Hilton less than 2 years ago and it was a fantastic feast that was WELL UNDER $20. 
I will give them snaps or should I say the front desk agent who checked me in. I arrived at 10AM looking to check into a king bedded room. None were available and the agent let me take a room with 2 beds for 5 hours unter a king was available! I thought that was very cool and virtually unheard of with most hotels. 
The pool and the workout room were small, but probably underutilized due to this being an airport hotel. It looks like they are readying a hotel floor renovation and none too soon. From a room standpoint, this is one of the "dumpier" Westins you will come acrossed. 
I'm not a light sleeper and sleep well in nearly all hotels. I can only say that this hotel must have some "trashy" hotel guest combined some with very thin walls. Between the very loud and obnoxious Filipinos who had no sense of it being 2AM or the rednecks who came in on the last Delta flight from Atlanta at 3AM, people had a total lack of respect in walking down the guest halls and deciding to converse outside of rooms.
If their staff acted licked they cared about the guests and showed some aggressive hospitality, I would have given them another star.
