Casino Review Only:
MGM has a perfectly fine casino - nothing special, but all of the bells and whistles. I have not played any table games here, but my friends played poker and said the dealers were good and knew what they were doing (which wasn't always the case at other places, like Excalibur).
The sports book here is mediocre. People talk it up, but I wasn't a big fan. It's only a few rows deep and very wide, which isn't so much the issue. Rather, the people here are probably the worst I have come across in Vegas. Not to say they're rude...but they're not friendly. Other places have terrific Sports Book employees (Paris is the best in my mind), but MGM's are not too great.
Bathrooms are relatively common and clean enough. They have a 24 hour Starbucks location which is nice. Could use a couple more (and better) places to grab a quick bite.
