Frommer's, June 25, 2008 In providing tips for people contemplating a cruise vacation, the writer of this article notes that all Holland America ships "can consult 24 hours a day (via phone or e-mail) with the University of Texas Medical Branch at Galveston and their Vista-class ships have a tele-radiology system that allows X-rays to be transmitted to a shore-side medical facility. (Princess's Sea Princess and Carnival's Spirit- and Conquest-class ships also have this system.)"
