8. Wynn Resort, Las Vegas
Total cost of construction: $2.7 billion
“It's not easy to make an American casino seem elegant, but impresario Steve Wynn has done it at his eponymous Strip hotel. This curvaceous copper-toned high-rise was built on the imploded ashes of the vintage Sands casino, where stars like the Rat Pack once played. Marble walkways inlaid with floral mosaics, jewel-toned carpeting, and windows letting in natural light all add to Wynn's genteel allure, " says Telegraph Travel's Las Vegas expert Sara Benson.
“This is one of the most elegant casino-hotels on the Las Vegas strip, in terms of both interiors and service, and the clientele, from jet-setting celebrities to royalty, reflects that.”
