The cruise industry is primarily segmented into four major market categories based on price, service level, and amenities. The Contemporary (or Mass Market) category includes giant "floating resorts" like Carnival or Royal Caribbean, focusing on families and budget-conscious travelers with high-energy activities. Premium lines, such as Celebrity or Holland America, offer a more sophisticated atmosphere and higher-quality dining for a slightly higher price point. Luxury cruises, including brands like Silversea or Regent Seven Seas, provide smaller ships, all-inclusive pricing, and personalized service. Finally, the Specialty/Expedition category focuses on niche destinations like Antarctica or the Galapagos, prioritizing education and adventure over traditional onboard entertainment.
