I expected more from this spa. The whirlpool is VERY VERY small. There's a dry and wet sauna that doesn't do justice. The spa is very outdated and I would question the sanitation of the place.
Staff inside the women's spa is OK, not friendly, but decent and border line helpful. Overall, I would give the SPA facility a 1 STAR.
However, I'm giving them a 3-star because of the service that I received. Got the 80-minute Swedish massage...that was fantastic and its pretty reasonable for being on the vegas strip. Only $150 (thank goodness for Spa Finder).
I probably won't come back unless I have a groupon or more spafinder... but I would rather fork out more money for better amenities
