Love hertz! With most of the reviews and experiences it is hit or miss. When you travel and plan your trip you expect all reservations and experiences to go along as planned. All of my trips through this airport for renting a car have been as expected. You get off the bus, take the escalator to the Hertz level, see your name of the board and walk to your car and leave. It's pretty easy...
What I really liked was the bus driver gave us the address to the car rental return center and address to the closest gas station. This is always the issue when you return the car as its so expensive if you do not too the fuel tank off.
What I did not like was the long bus ride to the car rental center...prepare at least 15 to 20 minutes for waiting and the bus ride. It is what it is so be patient and enjoy the beautiful weather in Phoenix.
