The nice thing about Las Vegas is that most of the entertainment is located within 10 mile radius of the strip, so renting a car may not be necessary. However, if you are wanting to visit some of our more prized off the strip landmarks like the hoover damn, red rock canyon or possibly Zion in UT or the Grand Canyon in AZ a rental car will be needed. Check out Expedia for some good deals on car rentals out of Harry Reid International Airport here.
