A directory of cruise lines and ships

Here is a listing of cruise lines and their vessels. One caveat: Many cruise companies prefer to sell through travel agents. It's best to book through an agent who specializes in cruises.

Listings marked with O designate open or restaurant-style seating. T marks cruise lines that follow a traditional assigned seating policy. B means both traditional and open seatings.
