Another in the series of Viking Ocean Cruises' 930-passenger ships, this is the first in the fleet to feature a high-tech planetarium. The 26-seat, domed theater links to the ship's telescope and shows 3D programs. There are photos of space exploration all over the ship, but otherwise the ship showcases the Nordic design favored by Viking in its other ships. With a snow room in the spa, a faux fireplace and reindeer skin throws on the couch, you know you're on Viking.
