People come to Las Vegas for a variety of different reasons. But those simply using the city as a base from which to explore nearby parks are probably a tiny minority.
Tourists into gambling, nightlife and an all-around typical Las Vegas experience tend to stay on or near the Strip. This area is home to a myriad of hotels and casinos, many of which are household names, such as Mandalay Bay or Luxor.
Las Vegas, however, is a fast-growing city with new residential areas being built each year, and much of the greater metropolitan area feels surprisingly normal.
Some good choices outside of the strip area include Tahiti All-Suite Resort, South Point Hotel or Aloft Henderson, just to name a few.
