This year will be 4th time in 5 years. It's great. Everyone's advice here is exactly right. The sports books get absolutely nuts and lines begin around sun up. So be ready if you want that. A lot of sports bars are now charging min tabs and such or hourly rates for tables. It's just the nature of the beast. If you want a new(er) place that is off the beaten path, make the trek out to M Resort - wow, gorgeous place, nice sports book, and great sports bar right next to sports book. Also, last year ROK at NYNY (across the street from MGM) actually had tournament watch parties every day during the day, and the drinks were stupid cheap. And they served food. You have to find things like that.
Enjoy - it's the absolute best time ever that weekend. I'll be at MGM that weekend as well.
