Cruises come in different types, each offering unique experiences depending on the waterway they navigate. Ocean cruises take place on large cruise ships that sail across open oceans, often covering long distances and visiting multiple countries or continents. Sea cruises are shorter distances within a particular sea, allowing travelers to explore multiple coastal destinations within a specific area. River cruises use smaller, more intimate ships that navigate inland waterways. These cruises are ideal for cultural and historical experiences, as they stop in cities and towns rather than major ports.
