Riviera is one of Oceania Cruises' two larger Oceania-class ships and the sister of Marina, built by Fincantieri and entering service in 2012. Carrying 1,250 guests, she pairs an upmarket, food-forward ethos, including a hands-on Culinary Center, with elegant interiors and a high space-per-guest ratio. She sails wide-ranging global itineraries.
