Under the parent CCL brand, companies include Carnival, Princess, Costa Cruises, Holland America, AIDA, P&O Cruises, P&O Cruises Australia, Cunard, Ilbero Cruises and Seabourn. CCL encompasses ten subsidiary brands. Within each subsidy, the type of consumers, availability of fleet, flexibility in itinerary and choice of destinations vary. With 24 ships in its fleet, Carnival has great flexibility and options for consumers to reach destinations by sailing from 19 North American departure ports. Consumers can change their itineraries anywhere from 3 to 16 days. Holland, rated “Best Overall Cruise Value,” has a 15-ship fleet that offers nearly 500 cruises from more than 25 homeports, with the option to visit all seven continents. Their rooms average 25-50% larger than that of CCL, and itineraries range from 2 to 108 days. Costa Cruises are an Italian-style European cruise line. The cruise line offers the largest selection of sailing dates throughout the Mediterranean and Northern Europe. Princess Cruise, operating a fleet of 16 ships on 115 different itineraries, offers cruises ranging from 7 to 107 days in length, while reaching more than 350 destinations around the globe. Cunard is a traditional luxury-type of cruise that began in 1840. The line combines these years of storied heritage and experience with the three youngest fleets at sea, made up of the Queen Mary 2, the Queen Victoria and the Queen Elizabeth. Seabourn Cruise Line has approximately six ships providing an intimate experience for consumers because of their smaller sizes, carrying fewer than 500 guests. The smaller size also allows this cruise line to travel to destinations where larger ships cannot follow
