All-inclusive luxury line Seabourn is at the top of its game with the all-suite, 450-passenger Seabourn Quest, the most recent of the three knockout Odyssey-class ships. Like its siblings, Seabourn Quest is stylish and modern. It feels as cool as a W Hotel — especially in the living room-like Seabourn Square — and as fancy as a Four Seasons, especially if you make a point of ordering Champagne at every meal.
