Overall this was a solid stay. If I could do it again I probably would have opted to stay at the regular MGM vs the signature. Even though they look like they are close because the casinos are so large it's still a solid 15 minute walk to the MGM and then another solid 15 minute walk through their casino to get to the strip.
But in any case the Signature is still close to the hustle and bustle of the strip and is a little quieter and classier. You get a much larger room here (they are all suite style) and majority of the rooms have balconies. We had a balcony and that was a huge plus. And if you are into golf this hotel is directly across the street from top golf which can't be beat.
Customer service is excellent. We arrived pretty early and after a long day of travel were hoping to check in early. At first there were no rooms but the concierge spent an extra twenty minutes finding us an available room which was so appreciated.
The rooms are very clean and spacious - a huge bathroom with a stall shower and a jacuzzi and the main room even has a kitchen area and a living room. If you are coming with a larger group this hotel definitely seems like the move. The towers are very large and each tower has it's own small private pool, plus you have access to the large pools at MGM. We actually really liked having the private pool so that we didn't have to fight to get a good spot.
Only dislikes were that they were very skimpy on the towels and the sink drains were really slow. Oh, and it would have been nice if the balconies had chairs. But just little minor things. So again, would opt to stay at the regular ole MGM because I value location over space, but if you feel the opposite and want some peace and quiet this is a great pick.
