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.
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!).

These rooms have stunning views of the city and/or the Strip from huge floor-to-ceiling windows. They all include a stocked mini-bar, expressive artwork, and an in-room safe.

Casinos: The Cosmopolitan or ARIA

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.
