I just returned from JW Marriott in Las Vegas. It is a beautiful hotel. I had just returned from a tour in Afghanistan and I was planning on book the "Active Military and Family Special" Rate of $127/night. However, I waited a day and when I tried to book it again, a government rate of $79/night appeared! Next to the JW in Kuala Lumpar, this is one of the best Marriott deals. I am not sure if it was an upgrade but I had a patio room (MR Gold). The rain shower was really a nice touch. My only complaint is that my stay was too short, one night.
