You can choose any car in the designated area of the parking lot without any staff present.

The self-service kiosks are very convenient.

Customer service staff had an indifferent attitude.

Alamo and National share the same location, and the cars are interchangeable. At the self-service kiosk, you can print the contract in about 5 minutes, then take it and choose your car. We rented a luxury car and initially saw only a Volvo S80, which was nice but we were expecting something like a Cadillac. We asked the staff, and they kindly checked for us, eventually bringing out a freshly cleaned Infiniti QX60. It turned out to be perfect for long trips over the two weeks.

It's very convenient to take the free shuttle bus with Alamo signs from the airport to the rental location.
