Alex,
Thanks for the stay. Great location if you want to be on the strip! Access to all MGM Grand resources/pools etc by being connected via moving walkways was great. If driving/parking there, just know you may encounter some frustrating valet parking at times. Often times when coming back to the signature, Id be in line for quite a while just to give the valet my car. Most days, the valet in tower 3 was totally closed so we were forced to walk to another tower for pickup/drop-off. Pickup usually was no more than a 10 min wait, but drop off delays caused us to miss several things we had planned. The one day I had to self park at the grand, the walk back to Tower 3 was a good 30 mins (all the way through MGM underground, lobby, casino, district, etc etc etc. Plan ahead for some delays and you will be okay. Probably not a problem for those that don't have cars on a trip. Also, heads up, pools close at 7pm, do don't plan on any evening swimming.
Thanks, Jeff
