Oceania Insignia

(11:21 a.m. EST) -- Oceania Cruises' annual world cruise is the longest on offer -- 180 days -- and the line has announced yet another half-year sailing for 2020 aboard Insignia. In addition to the notable length, the just-revealed itinerary will feature four equator crossings, the line's first South America circumnavigation on a world cruise and visits to 95 ports across four continents.

The voyage will depart Miami on January 8, 2020, and ends in San Francisco on July 5, 2020. Options for slightly shorter or longer cruises with different U.S. homeports can be accommodated, with routings roundtrip Miami (195 days) and San Francisco (162 days), or from Miami to New York (200 days), San Francisco to Miami (177 days) and San Francisco to New York (182 days).

Additional highlights include more time in Japan (nine ports) than on previous around-the-world sailings, stops in Africa, sailing around the Cape of Good Hope and Cape Horn, and a tour of Alaska from the Aleutian Islands to the Inside Passage. The itinerary features 38 countries, 17 overnight stays (some for two nights) and the possibility of visiting 67 UNESCO World Heritage sites. Special shoreside events will take place in Montevideo, Uruguay; Cape Town, South Africa; Rangoon, Burma (Myanmar); Hong Kong, China; and Kyoto, Japan.

"Travel is meant to be life-changing and that was our goal when we set out to chart this most monumental of world voyages," said Bob Binder, president and CEO of Oceania Cruises, in a news release. "The people you meet, the experiences you have and the places you visit will make an indelible impression which you'll cherish and relive for years to come."

Early-booking fares for around-the-world cruises start at $41,999 for an inside cabin (up to $145,999 for the Owner's Suite) and include many free perks, such as complimentary first-class airfare, prepaid gratuities, medical care, unlimited internet, laundry service, visas, luggage delivery and a one-night pre-cruise hotel stay. In addition, passengers can choose one perk from the following included options: 70 shore excursions, a beverage package or $7,000 in onboard credit per cabin.
