I love CityCenter. It's an architectural marvel. What's kick ass about it is not necessarily the restaurants, hotel rooms, spas, bars, gaming, etc. (though, those are all certainly good), it's the art. There are art installations everywhere you look. All nooks and crannies of the CityCenter buildings (inside and outside) are full of interesting art. And this makes for a fabulously fun, beautiful, and educational self walking tour. A great way to spend a day in Vegas that doesn't involve gaming. Hint: There's an app you can download that will tell you all about each piece of art.
