The Cosmopolitan opened on 15 December 2010 on a small plot between Bellagio and CityCenter, so it was built upwards: two glass towers of 50 and 52 storeys, with the restaurants, bars and pools stacked above the casino rather than spread around it. At $3.9 billion it was one of the most expensive resorts ever built on the Strip. Much of it was first sold as condo-hotel apartments, the developer defaulted, and Deutsche Bank finished it in a modern style with no theme. Blackstone bought it in 2014, and MGM Resorts has run it since May 2022.
There are 3,033 rooms, 1,412 of them suites; the large bathrooms are a leftover of the condo plan. The entry City Room is 460 sq ft (43 m²) with no terrace. Terrace Studios are 620 sq ft (58 m²), with a full-size bubbler tub and sliding doors onto a private 110 sq ft (10 m²) terrace. Terrace One Bedroom Suites put the bed behind telescoping doors and add a Japanese soaking tub, and the Wraparound Terrace Suites run to 1,200 sq ft (111 m²) with a 410 sq ft (38 m²) terrace. Most rooms were last redone in 2017 and 2018.
The reason to book is the terrace, and the side it faces. Private balconies are rare on the Strip, and the Fountain View categories turn one to face the Bellagio lake next door, where the fountains play every 30 minutes from 3pm on weekdays and from noon at weekends, then every 15 minutes from 8pm to midnight. The Boulevard Tower on the Strip corner looks straight up the lake; from the Chelsea Tower the fountains sit off to the right. From mid-September to December a temporary Formula 1 stand runs along the lake's Strip edge. A plain Terrace Studio may face ARIA instead, so the words Fountain View in the room name are what you are paying for. Downstairs, The Chandelier is a three-storey bar hung with two million crystal beads, open around the clock on its lowest level, and é by José Andrés, nine seats at a counter, holds a MICHELIN star.
The trade is upkeep and extras. A $55 nightly resort fee plus tax is added, self-parking costs $20 a day, smoking is allowed on the terraces, and recent guests keep raising worn fittings and uneven housekeeping in rooms that MGM plans to remodel after ARIA's. On Tuesday 18 May 2027 the City Room cost $215 a night before tax and the fee, and the Terrace Studio King Fountain View $258. You must be 21 to check in. Book it for couples and friends who want the fountains outside and the bars below, and pay for the view.
