The Cosmopolitan vs ARIA (Which Las Vegas Hotel is Best?)

If you’re planning a trip to Las Vegas and trying to decide between staying at The Cosmopolitan or the ARIA Resort & Casino, it’s important to know the differences between these two properties in order to choose the best hotel for your stay. So, how does a trendy hotel like The Cosmopolitan compare to the high-end luxury of the ARIA Resort & Casino on the Las Vegas Strip?

The Cosmopolitan is the right choice if you want a luxury hotel with a room that has an outdoor balcony overlooking the Strip. While ARIA is the best choice for those wanting to experience luxury in an ultra-modern property with a vibrant party scene. Both hotels have a prime location on the Vegas Strip.

The Cosmopolitan and the ARIA Resort & Casino are both 5-star hotels located in the heart of The Strip in Las Vegas. The Cosmopolitan aims for a feeling of private urban residence with luxury features, while ARIA prides itself on being technologically advanced with very modern architecture and amenities.

Both properties offer an impressive amount of services and features, so how do you choose between these hotels for your next trip to Las Vegas?

We’re going to compare The Cosmopolitan vs ARIA based on the criteria that is important to most guests when choosing a Las Vegas hotel. By the end of this article, you will know which of these Las Vegas hotels is the one for you.

The Cosmo vs ARIA: Standard Room Comparison

Both hotels have a selection of different room layouts available, however, for comparison’s sake, we’re going to compare what is considered to be the standard room for each hotel.

The Cosmopolitan: City Room QQ

The standard room at The Cosmopolitan is called the City Room QQ. With 460 sq. ft. of living space, and two queen beds, this room works well for up to four people traveling together and is great for families with kids.

The room comes decked out with the latest technology, including sophisticated entertainment systems. You’ll find a plasma-screen television that includes access to personal subscription services like Netflix and Pandora, as well as high-speed Wi-Fi. 

In addition, each room comes with a large luxury-style bathroom with a double sink vanity so multiple people can be getting ready for a night out on the town at the same time.

Take a tour of The Cosmopolitan City Room.

The City Room has large floor-to-ceiling windows (some of the City Rooms have smaller windows depending on availability) with views of the surrounding city and mountains, but it is the only level of room at The Cosmo not to have a balcony. One of the greatest features of many of the rooms at The Cosmopolitan is that they come with an expansive outdoor terrace with gorgeous views of the Strip (including a spectacular Bellagio Fountain view).

The Cosmo is the only major resort on the Strip to have balconies in the majority of its rooms (2,200 rooms out of 3,027 rooms have balconies), but in order to get a balcony, you’ll need to step up to the next sized room the Terrace Studio room for about $40 more per night (in my opinion the views are worth it!).

Casinos: The Cosmopolitan or ARIA

Both hotels have large casinos on their properties, with ARIA’s casino being slightly larger. 

ARIA Casino

ARIA, as befits a mega-resort in Las Vegas, has an on-site casino with 150,000 sq feet of gaming floor that includes slots, table games, and a race and sports book. The ARIA casino is different from traditional Las Vegas casino designs, however, because the architecture allows for natural light to enter through skylights and exterior windows (It’s strange but nice to see natural light in a casino!)

The Cosmopolitan Casino

The Cosmo, on the other hand, has a slightly smaller 110,000 sq foot casino where you’ll find slots, casino tournaments and events, table games, and a sportsbook. You can join the Identity Membership & Rewards program to receive points for every $1 spent in the casino and get exclusive offers to use in the casino, poolside, and other areas of the hotel.
