The Spa at ARIA Sky Suites

"We love the spacious bathrooms with their plush robes (to keep guests warm amid all the cold granite)"

"The spa is one of the only ones in the country to offer Japanese stone sauna Ganbanyoku beds, and boasts three private spa "suites," each of which serves up to eight people at a time"

"A spa and salon provide on-site primping and shops such as Louis Vuitton and Tiffany are just a few steps away in the Crystals shopping complex"

"This mega-hotel at the CityCenter has all the fixings: more than 4,000 rooms in a Five Diamond hotel, 16 restaurants, three pools, and a spa where you can recline on Japanese stone beds"

"Instead, its 4000-plus deluxe rooms (520 sq ft) and 560 tower suites (920-plus sq ft) are all about soothing design, spaciousness and luxury, and every room has a corner view"
