Country club chic perfectly describes the surroundings aboard Oceania Nautica — and many of the 684 passengers as well. Built in 2000, the ship underwent a major refurbishment in 2014, resulting in new cabin interiors and nice touches, like a no-fee espresso bar. Food is a big deal aboard, with vast menus (including items by affiliated Chef Jacques Pepin) served in the open-seating main dining room. The relatively small ship (just 342 cabins) carries big-ship amenities, like a Canyon Ranch Spa, a large heated pool, and a casino. Choose a Concierge Level cabin or suite for perks like early boarding, a Champagne welcome, access to the Spa Terrace, and 24-hour butler service.
