Oceania Insignia, which was built in 1998 for the now-defunct Renaissance Cruises, underwent a major refurb in 2014 but the public spaces still have traditional, plush furnishings befitting this "country club at sea." Oceania serves up some of the top food afloat: You'll find selections from Jacques Pepin, as well as diet-conscious recipes from Canyon Ranch at all of the eateries.
