You think there are bad connotations to "Vegas Planet"? I grew up in Las Vegas and when to Our Lady of Las Vegas parochial school. Now how 'bout those connotations?
Local and esoteric knowledge, like the fact that Las Vegas means "The Willows," to some, and sin to others. Not very important, I suppose, in the long run. Guess it was the way I was brought up. Can't shake the fact that to every one I grew up with Las Vegas was "a dirty name." Still, I like The Willows aspect of the city, and enjoyed that part, at least, on a visit to a friend. ;)
