Swimming pools are an enticing amenity when booking a hotel, but for adults traveling sans children, the puerile energy around pools can feel a tad too Splash Mountain. One minute you’re calmly floating in the deep end, the next minute, some Kevin McCallister is doing cannonballs near your head.

Another bummer is when pools shut down early—no time to take a dip after dark. (Is there any sentence worse to a traveler’s ears than “Pool closes at 6 p.m.”? We’re looking at you, Las Vegas!) If a moodier, more grown-up atmosphere is what you’re after, take heed: A number of hotels offer night swimming, bringing cocktails and entertainment poolside. Here are seven spots to enjoy an adult swim. (Check hotel websites for exact dates and times.)

Hollywood Roosevelt: Los Angeles

One of the longest running, most iconic late-night pool parties, NightSwim at the historic Hollywood Roosevelt is about as L.A. as it gets. Celebrity DJs spin at the 1960s-style Tropicana Bar, while an endless parade of entertainment industry folk—aspiring actors, models and other people who look fresh from the set of Vanderpump Rules—dance the night away, splash around in oversized canoes or pose for an underwater photo booth.

Prefer your nighttime swim with a side of stunning views? The rooftop pool at The Standard in Downtown L.A. offers just that—plus a rotating cast of party-starting DJs, a red AstroTurf deck, an outdoor fireplace, quaint German Biergarten and fantastic people-watching. Not a lot of swimming seems to happen, actually, but the heated pool is worth a wade.

Eclipse at Mandalay Bay: Las Vegas

The pool party is a Las Vegas staple—and one that seemingly occurs all day, every day. You probably picture a rowdy, sun-drenched soiree sponsored by some liquor brand and featuring special guest appearances by a Kardashian or members of The Bachelor franchise. But on Sundays at Mandalay Bay’s Daylight Beach Club, the party rages on into the night, as well. If you don’t mind the oonsta-oonsta of EDM or a pool teeming with people, the Eclipse nighttime concert series is an essential, what-happens-in-Vegas spectacle.

Loews Miami Beach: Miami

Raft races, limbo contests and dive-in movies are all part of the fun at Loews’ palm-fringed pool, which is open 24 hours. This South Beach luxury hotel, located in the colorful Art Deco District, is all about pampering guests. Think: Evian and suntan-lotion misting, fruit smoothies and frozen grape kabobs by day, and swimming peacefully under the stars at night.

Fifty stories up, the W hotel’s rooftop pool and lounge, WET Deck, offers an unquestionably scenic spot for night swimming and a cocktail. With breathtaking views of the city skyline and Biscayne Bay, the sky-high swim spot is the perfect place to spend a Miami night.

Miramonte Indian Wells Resort and Spa: Indian Wells, CA

The Miramonte resort in California’s Coachella Valley endeavors to combine “desert style and luxury comfort,” and among its more refreshing features are three swimming pools open until 11 pm. All three offer poolside food and drink service, but if you’re seeking an adults-only atmosphere, stick to the more serene, off-the-beaten-path Piedmont Pool.

Ace Hotel and Swim Club: Palm Springs

Experience desert nights, done a different way, at the always-buzzing, midcentury-modern Ace Hotel in Palm Springs. Musicians from L.A. routinely turn up at the Swim Club for DJ gigs, and don’t be surprised to also stumble upon poolside drag shows, art-film screenings, Tarot card readings, dancing and drum circles.
