If a seven-night cruise doesn't seem long enough, would 100-odd nights of lavish galas, hobnobbing with interesting fellow passengers and visits to faraway lands be more your style? If so, it's time to get a world cruise on your 2020, 2021 or 2022 travel calendar.

Around-the-world voyages have been around since Cunard's RMS Laconia sailed the first one nearly a century ago in 1922. Yet they remain popular today, thanks to continuing itinerary innovations by the cruise lines and modern technology that makes it easier than ever to stay in touch when you're spending 100-plus days at sea. You'll find sailings as long as 180 nights (on Oceania) while some lines -- like Cunard and, new for 2021, Silversea -- run two or more a year.

A few things to note: Many world cruises don't sail fully around the world, though they do offer a chance to see a varied portfolio of diverse cultures all in one sailing. Also, if you can't commit to a full world cruise, you can often book one "segment" of the voyage, ranging from a week to more than a month. World cruises typically begin in January and end in April or May, but some lines change it up with departures in other seasons.

Whether you want to dream big or live large, here's the rundown of 2020, 2021 and 2022 world cruises.
