On my way out of Vegas I stopped at the new "CityCenter" complex. Which, as far as I could tell, was neither much of a center nor much of a city. It's a collection of casino/hotels, a mall, and a residential tower, connected up by an airport peoplemover type thing. It isn't surprising that the residential tower isn't exactly doing well because I couldn't actually find any residential amenities in the complex, unless you count "casino" and "high end mall."
Doing it wrong...
