SO simple! Most of the rental car companies are in this building and you only have tot take one shuttle from the airport to it. (However cramped the shuttle may be). It was especially nice when Thrifty ran out of cars and sent us over to Alamo, who had taken some of their reservations. Getting the car was fairly easy and the garage was clearly labeled. Returning the car was easy as well. \n\nGoing back to the airport, there are several different shuttle lines, depending on what airline you are flying. This was a bit confusing at first, but we didn't have to wait for it.
