You’d never know you were in Sin City at The Spa at Four Seasons Hotel Las Vegas, as there’s no casino and, hence, no stroll—on the road to relaxation—through intentionally disorienting chaos. Once you wander into the hotel’s tasteful lobby, a representative immediately leads you to your destination. The Spa’s subdued décor is seamless. This intimate refuge swathed in mild tones is on the smaller side, so personal attention (in concert with The Four Seasons’ usual impeccable service) is a plus. Shuffling to the Zen lounge in one of the city’s plushest robes (no stealing, now), you sip cucumber water or tea and nibble on an array of treats from dried fruit to pastries. Don’t be surprised by the smell of fresh-baked goods either; fresh doughnuts are served in the lobby café, and sinful mini-chocolate muffins are omnipresent in the spa (finally, snacks you can get behind). The Spa’s services are some of the most effective and clinical of the Vegas bunch, so you’re asked to fill out a health information form at onset (frighteningly rare in Vegas spas). Opt for a unique results-oriented facial like the signature Vitality of the Glaciers ($275), an anti-aging RNA, DNA and collagen treatment that jump starts your cellular metabolism (plain English: it tightens things up and sets you aglow). Think you liked hot rocks on your back? You’ll leave the new Everlasting Flower stone facial ($235), with poppy seed exfoliation, hibiscus extract and rhodochrosite rocks, feeling relaxed.
