Depending on who you hired your car from, you will either have to return the car to the same parking area from where you picked it up, or drive it to a designated area for inspection. Staff from your provider will then make sure the hire car is in the same condition as it was upon your collection, and that you have replenished the fuel. For returns outside of office hours, there will be a provided drop box for you to deposit the keys into. Search car hire on KAYAK
