If you have one day on this planet and want a snapshot of everywhere then Las Vegas it is! The largest theme park in the world. Sure gambling is king but it is none the less an impressive jaw-dropping invention. For a city that has emerged from nothing in little over a hundred years and now boasts over one million residents and thirty times the tourists, you can't help but be taken in by it all no matter how much of a cynic you are. Who needs Venice, Paris, New York or Monte Carlo when you've got them all here in miniature and where you can still pay $20 to get married by Elvis? Viva Las Vegas!
