I went on a Saturday at around 430 pm and it wasn't too busy nor too empty (just right). Cover was 20 dollars per person and included entry to the pool as well (bonus for showing up on a Saturday).
The crowd and music was very lively. Beautiful scenery especially at sunset (both people and the location). See my posted pictures. The place had pool tables, a ping pong table and lots of seating space. The washrooms were well kept and the girls one apparently even had beds. If you forget your swimwear you can buy it there but the price tag is steep at $60.
We had no problem just showing up and getting a booth (without buying a package). I came with about 8 friends and we bought some food and 2 bottles (750ml) which came with 2 chase each. The bill at the end came upto around 550 after taxes and tip. This isn't bad considering it was split 8 ways. Drinks otherwise are $9 which I expected.
Cons: Service was ok. The place closes sorta early which is a shame at 9pm.
Overall it was a good chill experience and I would go back again with friends.
