DATAfile: Cruise Ships A statistical program is recommended. conde Nast Traveler Gold List for 2012 provided ratings for the top 20 small cruise ships. + The data shown below are the scores each ship received based upon the results from Conde Nast Traveler's Annual Rea mondents who rated a ship as excellent or very good on several criteria, Including Itineraries/schedule, Shore Excursions, and Food/Dining. ual Readers' Choice Sur ce Survey. Each score represents the percentage of an overall score was also reported and used to rank the ships. The highest ranked ship, the Seabourn Odyssey, has an overall score of 94.4, the highest component of which is 97.8 for Food/Dining.
