I've had good experiences at New York New York, though it is a bit more expensive than the places previously mentioned. With that said, you'll spend very little time in your room, so focus more on quality location than quality amenities. An Uber to the arena will probably be $15-20 from the heart of the Strip. Personally, I'm considering staying down on Fremont for this trip just for a different experience.
Anyone looked at flights out of anywhere in North Dakota yet? Allegiant is making a killing off this game.
