On weekends oftentimes there is a live DJ spinning by the European Pool. Get there before 9:30 if you want a chair! Also, try the mojitos and/or sangria. Delicious !
Cabana's are sweet, reserve them months ahead. The "cabana pads" down by the pool are additional/not included with your regular cabana and are around (as of today) $400 for the day.
The best bananadaiquiris in Vegas are served at the Encore pool. The East Side Bar right near the pool has a drink called the cherry bomb that is worth trying.
