Premier 57

The fancy former Spa Castle annex offers plenty of ways to calm your mind without having to set foot in those infamous hot tubs. Relax in one of five saunas—including a 14-karat all-gold sauna and igloo—designed to clear out toxins and help you breathe easily. Step into the meditation and sleeping rooms for quiet time to yourself. Best of all, if your introspection leaves you peckish, grab a smoothie or noodle bowl—or even a cocktail.
