ARIA Resort & Casino is one of the principal Las Vegas Strip ultra-luxury hotels — opened December 16, 2009 at the CityCenter complex, operating 4,004 rooms including 568 suites distributed across two curvilinear glass towers up to 50 storeys, and holding AAA Five Diamond, Forbes Travel Guide Five Star, and LEED Gold certifications. The property is owned by The Blackstone Group and operated by MGM Resorts International.

This piece is a 2026 configuration analysis of the property — the December 2009 opening context, the 4,004-room inventory, the Sky Suites and Sky Villas premium tiers, the LEED Gold environmental certification, and the position in the broader Las Vegas Strip ultra-luxury hotel set.

The December 2009 Opening

ARIA opened on December 16, 2009 as the principal property at the CityCenter complex on the Las Vegas Strip. CityCenter was one of the largest privately financed construction projects in US history at the time of completion — combining ARIA with The Crystals retail anchor and a series of additional residential and commercial components.

The December 2009 opening coincided with the broader recovery from the 2008-2009 financial crisis. The property’s opening framework supported the broader recovery of the Strip resort market and established ARIA as one of the principal contemporary ultra-luxury Strip resort properties.

The 4,004-Room Configuration

ARIA operates 4,004 rooms total including 568 suites — one of the larger Strip luxury hotel inventories. The principal accommodation categories:

Standard rooms: The principal hotel room inventory across the broader tower footprint. Each room includes a stocked mini-bar and a one-touch room control system allowing guests to customise lighting, temperature, and broader room features.

Sky Suites: Range in size from 1,050 to 2,060 square feet. The Sky Suite category is the principal premium-suite tier and supports both senior-traveller and entertainment-anchored use cases.

Sky Villas: Range in size from 2,000 to 7,000 square feet. The Sky Villa category operates at the top of the suite cabinet — the 7,000-square-foot top configuration is one of the larger ultra-luxury hotel suite footprints in the broader US hospitality market.

The Sky Suites and Sky Villas operate within the broader Sky tier programming, which provides elevated check-in, dedicated concierge, and access to specific Sky-tier amenities differentiated from the broader ARIA hotel programme.

The Curvilinear Glass Tower Architecture

ARIA’s principal architectural feature is the two curvilinear glass towers rising up to 50 storeys. The curvilinear design distinguishes ARIA from the more conventionally rectilinear Strip resort towers — providing a structurally distinctive visual identity on the Mid-Strip skyline.

The two-tower configuration supports operational flexibility:

• Different view orientations across the two towers
• Operational separation between sub-sections of the broader hotel inventory
• The curvilinear footprint that allows multiple view orientations across the broader Strip and Las Vegas valley

The architectural identity is one of the structural visual elements that distinguishes ARIA from the broader Strip resort competitive set.

The LEED Gold Environmental Certification

ARIA received LEED Gold certification for its environmentally friendly design — and was the largest hotel in the world to achieve LEED Gold certification at the time of designation. The LEED Gold framework reflects:

• Energy-efficient building systems integrated across the property
• Water conservation programming
• Sustainable materials selection in the construction and operational programming
• The broader environmental design framework that underwrites the certification

The LEED Gold recognition is one of the structural commercial differentiators of ARIA from the broader Strip resort luxury hotel set. Few peer Strip resort properties operate at comparable environmental certification tiers, and the combination of luxury hospitality recognition with environmental certification supports the broader contemporary commercial positioning of the property.

The AAA Five Diamond and Forbes Five Star Recognition

ARIA holds:

• AAA Five Diamond Award: The highest tier in the AAA hotel evaluation framework
• Forbes Travel Guide Five Star rating: The highest tier in the Forbes hotel evaluation framework

The combination of AAA Five Diamond and Forbes Five Star recognition places ARIA within a small subset of US luxury hotels at the top of both evaluation frameworks. The combined recognition supports the property’s premium-pricing position within the broader Strip resort luxury hotel market.

The Blackstone Ownership and MGM Operating Framework

ARIA is owned by The Blackstone Group and operated by MGM Resorts International. The ownership-operator split reflects the broader 2021-2022 CityCenter ownership reorganisation, in which Blackstone acquired the ownership of multiple CityCenter components while MGM Resorts retained operational management.

The structure provides:

• Blackstone: Capital and long-term real estate ownership with the broader Blackstone real-estate portfolio framework
• MGM Resorts: Operational management and integration with the broader MGM Strip resort portfolio including the MGM Rewards loyalty programme

For travellers, the practical impact of the structure is the MGM Rewards loyalty integration — ARIA operates within the broader MGM Rewards ecosystem alongside Bellagio, The Cosmopolitan (integrated July 2024), MGM Grand, Mandalay Bay, and the broader MGM Strip resort cluster.

ARIA in the 2026 Las Vegas Strip Luxury Hotel Set

In 2026, ARIA operates within the principal Strip luxury hotel set:

• Wynn Las Vegas and Encore: North-Strip Wynn Resorts integrated property
• Bellagio: Mid-Strip MGM property (Fountains; Conservatory; 3,933 rooms; Marriott Bonvoy Luxury Collection)
• The Cosmopolitan of Las Vegas: Mid-Strip MGM property (Terrace Suites; MGM Rewards since July 2024)
• ARIA Resort & Casino: CityCenter MGM property (4,004 rooms; AAA Five Diamond + Forbes Five Star; LEED Gold)
• The Venetian / Palazzo: All-suite Italian-themed integrated property

ARIA’s structural advantages within this set are:

• The 4,004-room scale supporting significant convention and group bookings
• The Sky Suites and Sky Villas premium tiers (up to 7,000 sqft)
• The AAA Five Diamond + Forbes Five Star + LEED Gold combined recognition
• The curvilinear glass tower architectural identity
• The CityCenter integrated complex with Crystals retail anchor
• The MGM Rewards loyalty integration

For corporate travel managers building Las Vegas premium hotel programmes — particularly with MGM Rewards alignment, large group booking requirements, multi-bedroom suite requirements (Sky Villas), or contemporary luxury hotel preferences with environmental-certification considerations — ARIA is one of the principal recommendations.
