City that never sleeps

Las Vegas, a city that offers people dream. A city that I only know through CSI and other tv shows. If it's possible, I would love to add this place to my near future place to travel since my colleague (she just came back from there on a business trip de-tour) told me that it's full of cool places to visit and fun, of course :p in the casinos. If you were there, and dunno where to stay, why not try the Orleans hotel Las Vegas ? Saw some review on it on the net ....
