Update: We went back to MGM after their renovation. This time we stayed in the West Wing.
After our amazing experience the first time, my wife and I were less than impressed with the West Wing rooms. They're pretty small and far away. Definitely the "low rent district" rooms. Our room had a broken lamp, stains on the carpet, and stains (maybe paint?) on the comforter and sheets.
We'll might stay here again because the service is great. If we do, we'll avoid the West Wing rooms.
