The document discusses the history of ocean liners and cruise ships. In the early 1900s, ocean liners transported people across oceans, with wealthy passengers in first class and poorer passengers in the lowest, most basic sections. Modern cruise ships offer all-inclusive vacation packages and aim to minimize stress for passengers through activities both on and off the ship. Cruises provide social, educational, and relationship-building experiences. Large cruise lines have multiple ships that can carry thousands of passengers each.
