The Best Cruise Lines in the World

4. Viking Ocean Cruises
Originally a river cruise line, Viking has launched six ocean-going vessels since 2015, the most recent being the brand-new Viking Jupiter, whose maiden voyage took place in February 2019. The fleet is nearly identical, carrying 930 passengers per ship, housed in balcony staterooms. Though not all-inclusive, Viking Ocean guests do receive one free excursion in each port (the ships primarily sail Northern Europe, though there are some off-season Mediterranean itineraries, too), beer and wine with lunch and dinner, and an unlimited Wi-Fi connection.
