Be sure to allow lots of time to get or return your car or you will miss your flight. It was 45 minutes from the time I walked out of the airport terminal to driving a car out of the garage (and I am an E-club executive member). Plan to wait in the heat at terminal for 15 minutes until shuttle bus arrives and then allow at least 15 minutes for the bus to travel to the rental terminal. The car windows were so dirty inside I had to stop to clean them before getting on freeway. When returning plan to stand outside in the heat for at least 15 min before the shuttle bus arrives (I did), then allow 15 minutes for the trip back to the air terminal. Shuttles are so infrequent they are fully loaded and have to leave people behind. Of all the airports (and Nationals) that I rent from, this is the most inconvenient so far.
