Depending on the supplier, the vehicle can be dropped off at the same place where you picked it up, and you might have to leave the keys in a key box.
The rental agent will clarify the drop-off procedure when you pick up your car. Your voucher will have the supplier’s contact details and address.
ℹ️ Keep your last fuel receipt until your deposit has been released by the rental supplier. Make sure to take pictures or a video of the car’s condition and note the drop-off time, especially if there’s no rental agent around when you drop off the car.
