We used Holiday which I know now is a third party booker for the company that actually provides the car. We were supposed to pick up a car in Keflavik Airport Iceland. When we got to the airport there was no information available to tell us where to get the car. My wife and I ended up wandering around the airport back lots in the rain trying to locate the office and car of the actual rental company Iceland Car Rental. There was no information from Holiday that told us the who we were actually renting from.
