Clipper Cruise Line will travel the Intracoastal this spring and fall (1-800-325-0010), as will another small line, American Canadian Caribbean (1-800-556-7450). In 1991 several lines with ships too large for the Intracoastal also visited Southern ports. These included Royal (1-800-622-0538), Cunard (1-800-221-4770), and Royal Viking (1-800422-8000). One of the Royal Viking Sun ’s trips was felicitously timed to allow passengers to attend Baltimore’s Preakness Stakes and the Spoleto Festival in Charleston. As of this writing, plans for spring 1992 aren’t set, but it’s worth checking to see if anything similar is on the schedule.
