Our room was fairly awesome. I was a big fan of the blackout shade you can drop to make your room impervious to sunlight.
The big drawback is the smell. As soon as you walk in, you are hit with a wave that smells like old lady perfume trying to cover smoke. It's highly unpleasant.
The casino is spacious and smoky. Should I deduct stars because I lost badly both nights I played here? Nah.
One must-do activity at the MGM is the Television City pilot-rating thing. You watch a TV pilot and rate it while it plays. Afterward, you get some coupons for discounted food. But it's awesome to share your opinion on new TV shows.
The buffet is decent, but avoid the disgusting Avenue Cafe.
This is an awesome place to hang your hat during your time in Vegas.
