ARIA Resort & Casino is a AAA Five Diamond hotel and casino on the Las Vegas Strip, part of the larger CityCenter development. Its casino floor, restaurants, and public spaces operate around the clock, seven days a week, so there’s no fixed opening or closing time for the resort itself.
Beyond gaming, ARIA is known for its contemporary art collection displayed throughout the property, a large spa, multiple pools, and a lineup of restaurants from well-known chefs. The resort’s curved glass towers and floor-to-ceiling windows have made it one of the more architecturally distinct properties on the Strip since opening in 2009.
Because ARIA functions as a full resort rather than a single attraction, most guests treat it as a multi-day base for a Las Vegas trip rather than a quick stop.
