We will arrive on sunday, 11-13-11 in Galveston after a transatlantic cruise from Europe. Anyone has an idea how to get to Houston International airport without using Carnival shuttle service(approx. 50 $ per person), taxi(50$pp) or a limo shuttle service(240$) for a 1 hour ride. I called Alamo, Enterprise & Hertz, all car rental offices are closed on this sunday! I am wondering, if anyone has an idea or maybe already used a good shuttle service to advise! Always happy cruisinÂ´!
