Our family of 5 recently stayed in Peter's penthouse. We were very impressed particularly after doing a lot of research prior to booking. In particular Peter was more responsive and informative than any of the hotels we had made enquiries with. When we checked in, reception and security at front gate were aware of our arrival and there were no negatives by not dealing directly with the hotels. The 2 rooms were of high quality and a perfect fit for our family as the 3 kids shared the 2 beds in one room and we had the other room. My wife pays more attention to detail than I so all I can say is the beds were extremely comfy, the showers nice and hot and the TV worked a treat. I used the MGM Signature gym and it was a little small but quite high-tec. The services within the building are terrific with a great cafe (hard to find in the US) that serves reasonable coffee and more European styled food. With respect to pools, you can use the Signature pool which is terrific in its own right. The spa is a good option too with the water very hot but comfortably hot. You can go really up market and go to the MGM pool (Signature customers can use all MGM facilities) small negative is the pools close at 7pm and I thought the pool drinks were a little overpriced (aren't they always) There are heaps of pools but our kids were fascinated by the whirlpool which is great entertainment value. We hired some rings realised we didn't really need them. Another reason that MGM signature was good for us was that we found it to be very quiet and we figured that the other hotels that had casinos would be a lot noisier and a lot more drunks. We didn't want our kids to be subject to that. In fact, even if I was just with my wife I think the Signature would be a better option as not only is it quieter but it appears to be a little more up market/classier than some other Vegas hotels. The chances of me going to Vegas again in the very near future are reasonably low but if I did go again my first point of contact would be Peter or at worst I would want a similar room within the MGM Signature.
