IF YOU WANT TO GO FOR THE LONGEST TIME: Oceania

Countries visited: 38 Ports visited: 70 Islands visited: 24 Nights in port: 17

The 2020 Around the World in 180 Days sailing aboard Insignia is one of Oceania’s longest-ever cruises. You’ll sail 18 seas, three oceans, travel 81,653km and access 67 world heritage sites.

The major ports you’d expect on four continents are visited, but the geographic scope of this cruise is more varied than Oceania’s previous world voyages: Alaska, the Aleutian Islands and the Inside Passage are included for the first time, for example, along with a circumnavigation of South America that includes the Falkland Islands.

If that’s not long enough at sea, add 10 or 15 days and conclude the trip in Miami or New York instead of San Francisco. From £33,459 (R630,000), or £185 (R3,500) daily, departing Miami Jan 8 2020.
