If you want to feel hip, modern, and cool (literally), we recommend grabbing your most fashionable swimsuit and heading over to the Hotel Palomar in downtown Phoenix. Sure, other hotel pools might be larger or more tricked-out, but none are more stylish than the Palomar's rooftop escape. Between dips, you can lounge in one of the plush poolside cabanas with a delicious cocktail from Lustre Rooftop Bar, just actual steps from the edge of the pool. And if you time your visit just right, you can bathe in the glow of the evening sun reflecting off the surrounding skyscrapers. We don't think there's any place that in Phoenix that feels more "big city."
