If you have plenty of time, and enough money, a world cruise may be the right choice. World cruises usually last for 90-120 days with fares ranging from USD 10,000 to USD 200,000 depending on the cabin and cruise line. A world cruise will take you to all continents and some of the world's best known cities and attractions.
World cruises typically circumnavigate the globe from west to east, and the voyages begin in Europe (Southampton) or the east or west coast of the USA/Canada. Routes vary, either travelling through the Caribbean and then to the Pacific Ocean through the Panama Canal, or by sailing along the east coast of South America and around the Cape Horn. From there ships usually make their way to Hawaii, the islands of the South Pacific, New Zealand, Australia, and then northward to Hong Kong, Southeast Asia and India. At that point again, routes may vary: one way is through the Suez Canal and into the Mediterranean; the other route is down the east coast of Africa, around Cape of Good Hope and then up the west coast of Africa. World cruises end in the port where they began.
Cruises heading east, however, are growing in popularity. The itineraries typically head east from Europe through the Suez Canal, India and Asia. The advantage of a west headed cruise is that the clocks keep turning back, which means longer nights every few days. The advantage of an east headed cruise is in a wider selection of northern ports of call.
World cruises range between 80-130 nights in length, but there are some 77 day options and even 365 day options. They typically begin in January and extent through April, but some world cruises start early (in November or December) or late (February or March). Unlike other voyages, world passengers have the option of partial sailings, usually two to three weeks in length. World cruise segment's departure ports are easy to find, they are available in most major cities in all continents. On any given world cruise around half of the passengers stay onboard from start to finish, sailing the entire voyage.
