There is no "advantage" in renting a car from Advantage. There were 3 people in front of us, and the wait was over an hour and a half. We originally had reservations with another company but decided on Advantage to save $20 bucks. Worst decision ever! I would have gladly paid that to get going with my vacation. The shuttle service to the McCarran Rent-a-Car Center is top notch... there is always a shuttle waiting in the lane, and never any waits. I wish Advantage would take a page from their book on efficiency. Pay a few extra bucks and utilize Alamo with the easy online check-in service, skip the counter, and choose your own vehicle. We've also rented from EZ from this facility and had a much better experience than Advantage.
