For the most part there are 3 major cruise lines that operate most of the major brands. Each brand has its own style and each appeals to different demographics. Although they will all tell you they are for everyone. Carnival has their base line,
Carnival which they advertise as the "Fun" line and then they have HAL, Princess and Cunard which are more upscale and laid back and appeal to a different group. They also have Costa, P&O, Aida which cater mainly to areas outside of North America.
Royal Caribbean has their base line, Royal Caribbean and also offers upscale lines Celebrity and Silversea as well as Pullmanteer and TUI which service other regions.
Norwegian has their base line Norwegian Cruise Line and upscale Oceania and Regent Seven Seas.
Each brand and line is a bit different in what they offer and the ships.
