A few friends and I recently came here over Memorial Day Weekend for a cabana. Finding the pool was a bit difficult, but they did have a couple of signs within the casino that helped. It's located on the rooftop of the first hotel tower, up the escalators and down the first hallway on the left. We ended up parking in the Downtown Grand self park garage and got our parking validated at the Players Club desk which was nice.
The pool itself was nice, different from the usually 2-3 ft pools on the strip. It was infinity style and a decent size to accommodate everyone. Besides the pool they had some games on the desk area like beer pong, foosball ball and bags which was cool. Seating wise, besides reserving a cabana, it didn't seem like there was a ton of available seating and it was first come first serve. As for music they had a DJ who played the violin which was interesting. She played mainly edm and some 80's rock, fitting for downtown.
For food and drinks the prices were expensive as expected, but not terrible. I ordered the Chips & Guac as an app for $12. The flavor was awesome and it was a decent portion. For a drink I ended up getting the lemon souvenir cup because I thought it was adorable. It was around $45 for the initial cocktail and $20 for refills. They also had bottles available for purchase, around $300 for a bottle of Grey Goose. (Much cheaper than Strip day clubs) They also had complementary citrus water sitting out for grabs and provided a fruit tray along with our cabana.
Overall I had an enjoyable experience and would come back again.
