I arrive in Las Vegas every 6-8 weeks . . . I rent a car, each and every time there. From Terminal 3 and the JetBlue portals, it's a quick walk to the service buses and on to the Car rental center. It's fast . . . the car vendors are right there ! Most of the time, I'm in and out within 15 mins. Good setup . . . good shuttle service . . . fast in and out ! What more do you need ?
