The room I got was big and fairly updated in terms of decor. Very clean and simple. Parking is far from lobby and elevators IMHO but wifi was fast and tub was huge and the shower was separate. I forgot what kind of double queen I got but I really enjoyed it.
In and out parking at all MGM guests is now $10 until 11:59 pm the day you check out. Just wave your key card at the area on the parking machine. Honestly I feel it should be discounted if not free for guests since there is a resort fee.
The worst was the coffee. It's no nespresso and not worth the price.
Service was wonderful. I would stay here again even though it's kind of off to one side of the Strip that's not all that great if the price was right.
