The main difference between Aria and Cosmopolitan is that Aria offers a calm, polished luxury experience built around spacious rooms, smart technology and refined dining. Cosmopolitan delivers a bolder, social atmosphere centered on nightlife, design and private terraces with Strip views.

What is Aria and What is Cosmopolitan?

Aria Resort & Casino is a large luxury resort in the CityCenter complex on the Las Vegas Strip. It opened in December 2009 and has roughly 4,000 rooms and suites.

Aria is known for its curved glass towers, sustainable design and LEED Gold certification. Rooms include in-room automation that lets guests control lighting, curtains and temperature from a tablet or bedside panel.

The Cosmopolitan of Las Vegas opened in December 2010 between Bellagio and CityCenter. It has about 3,000 rooms, and many of them come with private terraces overlooking the Strip or the Bellagio fountains.

FAQs

Can you walk between Aria and Cosmopolitan?

Yes, the two resorts are close enough to walk between in roughly 10 to 15 minutes, depending on where you start inside each property. The route passes through CityCenter and the Shops at Crystals, which offers indoor, air-conditioned stretches that help during hot weather. Guests can also use pedestrian bridges and walkways that connect the area, making it easy to dine at one resort and spend the evening at the other.

Are resort fees charged at both Aria and Cosmopolitan?

Both resorts charge a daily resort fee on top of the nightly room rate, which is standard practice on the Las Vegas Strip. The fee typically covers Wi-Fi, fitness center access and certain other amenities, and it is applied per night regardless of how much you use those services. Rates change periodically, so it is wise to check the exact amount during booking and factor it into your total budget when comparing prices.

Which resort is more family-friendly?

Aria is generally the better fit for families because of its calmer atmosphere, larger rooms and less party-driven environment. Cosmopolitan welcomes guests of all ages, but its nightlife focus, crowded bars and adult-oriented pool events make it better suited to grown-up travelers. Families visiting either property should note that Las Vegas casinos restrict minors from gaming areas, so planning routes around the casino floor is helpful.

Do Aria and Cosmopolitan offer parking for guests?

Both resorts provide self-parking and valet services, and parking fees apply for most guests at MGM Resorts properties. Some higher MGM Rewards tiers include complimentary parking as a membership benefit, which can lead to meaningful savings on longer stays. Rates and policies can shift, so travelers driving into Las Vegas should confirm current pricing before arrival to avoid surprises at checkout.

Is it worth paying extra for a fountain-view terrace at Cosmopolitan?

For many guests, a fountain-view terrace is one of the highlights of a Las Vegas trip and justifies the higher price. Watching the Bellagio fountain show from your own private balcony creates a memorable experience that few other hotels can match. If you plan to spend significant time in your room or are celebrating a special occasion, the upgrade often delivers strong value compared to a standard city-view room.

How far are Aria and Cosmopolitan from Harry Reid International Airport?

Both resorts sit roughly 10 to 15 minutes by car from Harry Reid International Airport under normal traffic conditions.

Travel time can increase significantly during peak hours or major events, so allowing extra time on departure days is a smart move.

Can non-guests use the pools at Aria or Cosmopolitan?

Pool access at both resorts is generally reserved for registered hotel guests, with room keys checked at the entrance. Non-guests can sometimes gain entry by booking a cabana or daybed, or by attending special pool events that sell tickets to the public. Policies vary by season and day of the week, so contacting the resort directly is the best way to confirm current access rules.

Which resort is better for a first-time visitor to Las Vegas?

First-time visitors who want to soak in the classic Strip energy and walk to nearby attractions often enjoy Cosmopolitan’s lively, central setting.

The right choice depends on whether the trip focuses on nightlife and exploration on foot or on relaxation, dining and a more refined pace.
