Most rental desks are located at the airport terminals or can be reached by shuttle bus.
At a counter, you will need a valid driver’s license issued in your name and your ID.
The supplier will put a hold on your credit card as a security deposit against damage.
Be on time, or it will count as a no-show, and the supplier may refuse to rent a car for you.
Look over the car for damage, take photos of any scratches, and check for the type of fuel.
