My only qualm with this hotel is that it is so far down on the strip. Other than that its a great stay.
The pricing is reasonable, and the view is very pretty. I really liked the rooms here and the bathroom was large with an inviting tub that I soaked in each night I stayed here. Unfortunately when I stayed here I was only 20 and could not partake in the games, but I did take advantage of the pool! The wave pool is fun and if you time it right you can ride the wave into the 'shore'. The lazy river is okay- I wasnt a huge fan as the waterfall knocked me off my tube twice, and drunk fools were making fun of me. Bah!
Great food options here at Mandalay Bay as well as the shark reef. I really liked Aureole (i'll save that review for later).
Also this hotel connects to Luxor and Excalibur so there's a lot to explore.
