We went on one of the last weekends it was open this year..
The weather was OK. Some overcast around 3.. which made it a little cold. It definitely wasn't as packed as I expected it to be.. but actually, Vegas wasn't that packed either that weekend.
Can't complain about the line, there was no one in line when we got there. 2ish? And we had a bed already set aside because my friends were already there. The pool was a nice and comfy temperature, the beds were large and comfy too. The drink list was interesting.. we ordered a few pitchers of mixed drinks. I only tried the Xtreme Passion, which was delicious (other than the brain freeze), but lacked any alcoholic punch.
The music was good. There was a point when it was house music which I don't care for.. But they also played hip hop and dance, which is more my style.
The only other Pool Party I've been to was Rehab on Memorial Day weekend, so this one pales in comparison of HARD PARTYING. It was a nice relaxing day at the pool w/ loud music. I'll have to try another day when Vegas is busier.
