The 700-passenger Seven Seas Voyager is a midsize ship that features a big-ship lineup of activities, with four dining options as well as a full-service spa and a casino. The all-suite, all-balcony ship has truly spacious cabins, with the smallest suite measuring a whopping 356 square feet. Best of all, the cost of a sailing includes round-trip airfare, shore excursions, and all beverages ... even those from the minibar.
