For wildlife lovers the draw of this ship is simple: The 28-passenger Zambezi Queen is a safari lodge that sails on the waters of Botswana, with daily excursions along the Chobe River for wildlife viewing. The three-deck ship has 14 staterooms (measuring from 215 to 300 square feet), while the top deck has a small tub-like pool at the bow plus outdoor decks at the bow and stern. AmaWaterways books four-night cruises on Zambezi Queen as part of longer itineraries that include time in Cape Town and at Victoria Falls.
