The Aria has drawn massive praise for its futuristic towers and innovative design, and this mega-resort is truly unique among all the other accommodations in Las Vegas. Smack dab in the middle of the enormous CityCenter complex it looks pulled from a science-fiction landscape, and its glass-clad curves and light-filled interiors are breathtaking. It's also one of the more expensive options, but those who can afford it should waste no time in booking one of their SkySuites, upper-floor rooms with killer views and every perk imaginable. The casino, at over 150,000-square feet, is one of the largest in the city, and those here to gamble will be more than pleased with the attentive service at the tables and the professionalism of the dealers. More than a dozen restaurants and four nightclubs are also scattered around the grounds, so there's plenty to do when you're not gambling the night away. Foodies take note: most of the on-site restaurants - including Julian Serrano and American Fish - will deliver to your room if you ask.
