Got to this pool an hour before it was about to close and these girls passed by us and told us "just say Cabana 9" and we just rolled in for free....YES! This may not work for you, but making friends wherever you go will always make your life better :)
This pool area is huge. First off, they have a LAZY RIVER...not to mention four or five other major pools and a hot tub. They play music and serve jello shots, drinks, food, etc.
My favorite thing to do is Vegas is Day Parties so I would definitely hit this place up early if you want to have an amazing time. I will say that there is a LONG walk through MGM to get to the pool area, but it's definitely worth it!
