I took a chance about 3 weeks ago and booked mine up at the MGM Grand for 4 nights. £475 including flights and I WILL GET A TICKET FOR THE FIGHT lol (positive thinking)
I tried emailing the concierge at the MGM Grand because on the website they mention if any guests staying at the hotel need tickets for events at the Grand Garden Arena to call or email and they can sort it out. I tried blagging some tickets before they are released but I got a response saying she can't save me 2 as the demand is gonna be high. Dammit, worth a try though!
