Great place to stay. The staff was very friendly, and helpful. There were only a couple downsides. One was the valet parking. Sometimes it was great, but other times it took 45 minutes. One time after waiting 20 minutes in line they told us the valet was closed so we had to park all the way at the MGM Grand Self-Parking, and walk the 30 minutes back to the Signature. The other downside was that on our last night we found a rather large, and nasty looking stain on the duvet. It was late, and our last night, so we just wadded it up, and put it in the corner, and used the extra blankets in the closet. Not necessarily the worst thing I've found in a hotel room, so at the time it wasn't the biggest deal for us. All in all it was a good stay, and I would definitely recommend.
