Passengers board a large ship that functions as both transportation and floating resort, visiting a series of ports while sleeping on board. That voyage is a cruise. It packages travel, accommodation, dining, and entertainment into one product.

Cruise ships range from intimate expedition vessels to large ships carrying thousands of guests. Itineraries may focus on warm-weather beaches, scenic coastlines, river cities, or remote polar regions. Onboard offerings include restaurants, shows, pools, and organized activities. Shore excursions are sold separately in most cases.

The industry has grown through larger ships and more diverse destinations. Environmental impact, port congestion, and public health management are ongoing challenges. For many travelers the appeal lies in unpacking once while still seeing multiple places.
