Vegas pool season typically runs from March through to October, with Sunday the most popular day to splash about. With a 54,000 square-foot saltwater pool complex, WET REPUBLIC AT MGM GRAND is big, loud and a favourite of models and sports stars. THE LIQUID POOL LOUNGE AT ARIA has just eight grand cabanas and makes for a more intimate experience, while SURRENDER AT THE ENCORE transforms into a beach club and offers night swims every Sunday. DRAI’S BEACH CLUB is also a popular option thanks to its position on the Cromwell rooftop.
