When you're deciding where to stay on vacation, you're weighing a ton of factors: location, cost, room features, views, and more. But there's an under-the-radar amenity that we highly recommend you keep an eye out for next time you book a trip. It's two little words, often in parentheses, on the part of the website where the property casually mentions the pool: "(24 hours)."

A pool that never closes. Think about it: you have a nice dinner, finish with a few drinks on the patio of the hotel's bar, and then - then! - you throw on a bathing suit and go for a dip in the pool or sink into a hot tub for a bit before bed. At 1 a.m. When you are literally the only person out under the stars. Does it get any better than that? To provide a little inspiration as you plan your Winter getaway, here's a sampling of chic spots around the globe that let you partake in the water amenities even in the early-morning hours. Happy splashing!
