Aside from the light-filled check-in area, Aria lacks an aesthetically appealing interior. Aria casino is dull-brown, foreboding, and underlit, which failed to induce this normally eager blackjack player to take a seat at a table and play a few rounds. And with so many Vegas restaurants approaching theatrical sets, Aria's are pleasant but relatively uninspired. We also found the bursts of bubblegum-pink spaces in a lobby bar and Chill, the gelato parlor, a discordant note in what otherwise resembles a corporate environment.
Perhaps if Steve Wynn's Bellagio, Wynn, and Encore casino-hotels hadn't raised the bar so high — they are truly striking-looking — the disparity wouldn't be so obvious. Palazzo and The Venetian also delight the eye, as does CityCenter's own Mandarin Oriental, Las Vegas.
A few other things disturbed us about Aria: The beds are sink-in soft and have no back support. Guest room sound-proofing is not great. We could hear another guest’s TV late at night, and the sound of running water from a shower elsewhere.
Additionally, cell phone service was spotty and particularly poor for visitors using Verizon and AT&T phones.
Last, when we visited Las Vegas it rained and rained. Yet the architects had not seen fit to build any passageways between CityCenter buildings to protect visitors from rain or desert heat.
