These four yachts, the largest of which carry a maximum of only 450 passengers, navigate global waterways inaccessible to larger ships, like the Amazon's Breves Narrows. "We felt as though we were on a luxury yacht, not a cruise ship." Staterooms with honey-colored wood have barometers, balconies or five-foot windows, walk-in closets, and sitting areas "where you can unwind with the sea breezes flowing in." In open-seating dining rooms, "the cooking is truly first-class." Of excursions, "the best was the evening in Ephesus," where staff set up dinner and "we listened to a symphony play on the steps of the Celsus Library." "Staff treat guests like VIPs." Seabourn Sojourn will debut in June 2010; its two-deck spa will have a Kinesis wall.
