Is it possible to rent a car at the airport, (Hobby or George Bush), drive to Galveston and turn the car in at the cruise terminal? I saw where Hertz and Enterprise have locations at Terminal 1, as well as Hobby airport, the closest airport to terminal. Does the Grand Princess leave from Terminal 2? I have called 800#'s and the people say they don't go to Galveston. Has anyone got updated info on this? The Bush airport is 90 min away and could get quite expensive. Thanks in advance
