It's not located in the best spot ever (off the main strip) but the Westin had a lot of things going for it.
Fast check-in, fast valet service and free wine, beer and snacks at 5:30PM
The beds are SO comfortable. I mean really nice with lots of pillows. You can really get a good nights sleep even after consuming large amounts of alcohol. The bathroom was very clean and even had a hair dryer and a scale (?) along with all the usual shampoos, lotions and sewing kits. TV was not new but then again, I'm not in Vegas to sit on my ass watching TV.
The pool area is small (but then the whole hotel is on a smaller scale) but has excellent quality comfortable lounge chairs and nice big umbrellas (for those of us with less then adequate amounts of pigment). There is even one of those mist spraying thingies above some of the loungers. Pool itself is small but clean and it was fairly quiet with almost no screaming splashing children. Spent quite a few hours up there. Nice bartender too who kept giving me water with a smile.
The location isn't as good and you have to walk by some sketchy establishments on the way to the strip but overall the quality of everything was just as good if not better then some of the major hotels (I'm thinking of you Planet Hollywood).
