If transportation prices are comparable to Port Canaveral and you have at least 4 ppl it is cheaper to hire a car service vice taking the DCL bus service. I know many of the hotels near the port offer complimentary transportation to the port. I would definitely price out transportation companies that mention cruise transfers. I've done this for Orlando on Florida cruises very successfully. But I've not cruised from Galveston before and will be driving. I did find this link with a few companies to start. http://transportation.destinationnext.com/
