Didion Cruises has been sending Alexandrians on world cruises since 1980, selling travel packages that range from one to two nights to more than two weeks. Serving all major cruise lines, including Carnival, Disney and Royal Caribbean, the company also runs weekly specials for new and returning customers. Didion was formerly located at 820 North Fairfax Street in the Montgomery Center, where the business name is imprinted on the building in big, blue letters, but is now located just steps around the corner at 300 Montgomery Street.
