The suite is nice, standard MGM Signature setup and decor. It is well maintained, but is slowly starting to show it's age with a few scratches, a dishwasher that could need some TLC etc. Nothing too surprising; the Signature has been there for a while.
Everything was comfortable and clean, the only challenge we had was with the valet parking, the only option at the Signature. After arrival on Friday night we wanted to go grocery shopping (~9pm) and were told that we of course cold get the car out of valet, but that we likely could not get there car back in valet when we returned as they were full, and would have to do self parking at the MGM Grand and walk from there. We decided to walk to the strip and pick up a few things at the little Target there instead.
Saturday we went to a show and when we returned we had to do the self parking. Sunday we went to a wedding, and upon return around 6pm it took liked 15 minutes to get to just leave the car in the general area of another towers valet. It got parked at some point in time I guess, but...
We liked the suite and the staff, and the owner it's AWESOME and super responsive! But if we drive to Vegas next time, this might not be our first choice, due to the parking situation.
