With a fleet of more than 35 vessels, Viking River Cruises offers tours on the world’s legendary rivers, such as the Nile, Yangtze, Mekong, Danube, Seine and Volga. For dinner, passengers enjoy open seating options and signature foodie events that emphasize local dishes, from Balkan cevapcici to Provençal lemon sorbet to Hungarian goulash made with paprika from a farmers' market in Budapest. (Local enough for you?) The ships contain all outside-facing staterooms, two-room suites with French balconies on Viking Longships, and the Viking Culture Curriculum. The latter is an onboard program that varies by ship and could mean having tea with a Tibetan family or learning how to make Germany’s brandy-laced Rüdesheimer coffee.
