No other city has the flashcard recognition of Las Vegas. Mention its name and you evoke images of luxurious resort hotels, high-stakes gambling, fast-paced production shows and a sort of frantic pursuit of adult entertainment that lasts 24 hours a day. Visitors come to Las Vegas to have their senses stimulated and bombarded and perhaps to break a few rules along the way.   Las Vegas is, first and foremost, a tourist town. Each year more than 30 million visitors stream into the city for nonstop gambling, hearty buffets, megaresorts and around-the-clock fun. But theres more to the city than that. Beyond the flamboyance of this adult amusement park is an exotic desert landscape just begging to be explored. Now more than ever, kids are welcome, too, with many activities and attractions planned just for the younger set. And newcomers are attracted by a robust economy that seems to have an insatiable appetite for employment.   Las Vegas Mccarran Airport serves this city through many airlines, including Virtual America West Airlines. Enjoy your stay!
