I've stayed at the MGM many times and every time I drop by here. It is centrally located, near the elevators and main lobby. Chill place to people watch.
Comfortable seating lounge. Can get a bit tight when packed. Decent place to relax and have a drink and/or meet up with friends for pre-party or getting that one last drink before heading to the elevators for a snooze at 5am. Drinks are Vegas prices. oh well.
