Bare pool at the mirage.
$20-40 to get in for guys. Girls free.
Drinks are about $15
Day beds and lounge chairs required $100+ tab when we went. If u dont want to spend the money your only option is sitting on the edge of the pool.
Pool area is fairly small, and laid back. Crowds can change depending on what day u go. My wife and i went on a sunday and it was about 50/50 guys to girls. Ages 21-50 or so. We went late on a friday and there were about 5 girls to the 40 guys. We didnt stay long.
The pool is topless, so expect about 1/3 of the women to ditch the tops.
