Decent service, organized and orderly car rental area (all the car rental agencies operate through a large hub south of the airport so you go to the same place for all of them) and the opportunity to rent a Vette for my stay in Vegas make this a great place to rent from.
I love that Hertz has performance cars available as part of its Fun Collection - you can't do much better for a rental car while in Vegas (without paying an arm and a leg for exotic car rental) than the Corvette ZHZ. Now, I'm not a Vette guy, and the car is technically outstanding - think 450 horsepower 2 seater sports car with lots of creature comforts and traction and handling controls - but it's everything you want for tooling around town or stylin' on the strip. Nice sound system, GPS, individual climate control, push button start, etc. It is a HELL of a lot of fun . . . so if you want to do Vegas right . . . get thee in a 'Vette!
