An ocean voyage is a journey across the sea, usually on a large passenger ship known as a CRUISE. Cruises are popular vacation options for travelers who want to explore the world's oceans and experience the beauty of the open water. They often include stops at various ports of call, allowing passengers to explore different cultures and take in the sights of the places they visit. Cruises can range from short weekend getaways to longer, more luxurious trips lasting several weeks or months.
