Viking Ocean Cruises’ third oceangoing ship doesn’t tinker with the line’s magic formula for success. Instead, the 930-guest Viking Sky offers the same great features found aboard sister ships Viking Star and Viking Sea, including the infinity pool and Scandinavian spa. The spacious ship is hard not to fall in love with, especially with its complimentary WiFi, shore excursions, and mealtime beverages (including beer, wine, and soft drinks).
