Las Vegas is apparently hot in more ways than one.  The Nevada desert city is topping a new Orbitz.com poll of the sexiest U.S. cities.

Miami ranks second, while New York City has the number three spot on the list.  Aspen, Colorado and San Francisco round out the top five.  Paris is number one among international locations, followed by Rio de Janeiro.  Tahiti and St. Tropez are also in the top five, along with Barcelona, Spain.  When it comes to the components of a sexy city, 32-percent believe the location or scenery is the most important aspect.  Just under 30-percent believe the "personality of a city" is key to making it sexy, while 13-percent feel the nightlife is what makes a city truly hot.
