Voyager Club (which recently celebrated its 25th anniversary) is available only to those who book their cruise travel through a Virtuoso-affiliated travel agency. The program offers complimentary benefits on the world’s finest cruise ships across hundreds of annual departures. Since 1990, roughly 400,000 cruisers have participated; in 2015, there will be over 300 shore excursions in 120 ports of call and 68 countries.
