I believe it usually sells out. Last year, I think I read it did sell out. If you are receiving free rooms, perhaps call the casino host and ask about "comp" tickets. If you have enough "play" to receive free rooms, food, etc. - than concerts, shows and this event is not out of the question.

Many other hotels, also block seats to events like this - to lure "high rollers" in for certain weekends. I looked and there are still seats available for the lowest prices (as well as the highest, and almost every price point).

LAS hotel/casinos bring people in for all kinds of big events - NASCAR, Rodeo Finals, Boxing, Concerts, EDC, Etc, etc. This is not a big event.

The MGM arena can hold 16,800 people. Less for hockey.

Safe travels and enjoy your stay in my "fair" city of LAS!
