The Best Cruise Lines in the World

5. Seabourn Cruise Lines
Don’t think of Seabourn as a typical cruise—it’s much more akin to a mega-yacht, with ultra-luxurious decor, service, and dining. The fleet currently has five ships, the largest of which carry 600 passengers—their small size allows the vessels to dock in small ports all around the world (in Indonesia, for instance, they’re partnered with the local tourism boards in developing ports like Celukan Bawang and Probolinggo). Many of the cruise line’s guests are lifelong learners, and they flock to the nightly Seabourn Conversation program, which brings all sorts of intriguing figures, from Steve Wozniak to Elaine Paige, on board for lectures and casual chats. In 2015, Seabourn announced a partnership with celebrity chef Thomas Keller, who crafted new menus for the three existing ships and spearheaded new restaurants on the two newest ships, Seabourn Encore and Seabourn Ovation.
