Cruises that cover several different countries and continents can be wonderfully exotic and enriching. While some are a few weeks long, others stretch to more than 100 days - with stops in Australia, Europe, North America and South America. Some even include sailing through Antarctica Sound!

With many days at sea, world cruises allow passengers plenty of time to indulge in the spa, dine round the clock, take in onboard entertainment or make new friends by the pool. World cruises may not be for everyone - but if you'd like to experience many different cultures in one trip, cruising is an incredibly hassle-free way to do just that. After all, on a world cruise, you can visit many different cities and countries, and you only have to unpack once!
