I've stayed in far better hotels in Vegas & wasn't impressed with the MGM. Was here for a week for work and staying in the West Wing. As soon as I walked into my room (14-511) I was greeted by the restroom.... no really...you walk in and see the wash basin. Super weird. After unpacking I discovered the drawer right under the TV was broken. Called up housekeeping...but they told me to call up maintenance...seems like this is a pretty regular occurrence as no one sounded surprised. Since I was barely in the room and out for work the entire day, I would have ignored all this if the bathroom had proper hot water. Not only was the water pressure terrible, the water was barely lukewarm. Again...calls to housekeeping didn't do much.
Compare this to the Aria or the Cosmopolitan which have stellar customer service.... MGM in general seems to have a pretty lackluster attitude towards their guests.
The place itself is a meandering maze...it takes at least 7-10 minutes to get to the elevators from your room.
Pros:
3 Starbucks cafes - one is hidden behind the "Show tickets" booth opposite Centrifuge and always nearly empty
The Food Court - labeled as "The District" - so you can get a bite without breaking the bank.
Overall, MGM needs a major customer service re-haul. Wouldn't opt to stay here with so many better choices.
