When I look at the San Diego airport website page on car rentals, it makes it seem as if all the car rental companies are away from the airport, and that you need to take a shuttle bus to get to them. My brother swears he rented a car right at the airport. Do any of you have any experience with this? We currently have a reservation through Enterprise, but I'm wondering about changing it. Our flight home leaves early in the am, and I'd hate to waste too much time getting from the rental car place to the airport...
