Just off Adventure of the Seas.  We made friends with a 13 year old boy from Long Island who was doing the scavenger hunt seeking the names of crew members from all the nations.  He literally worked day and night and spent hours tracking down the guy in the Windjammer from Belarus (who wasn't even on the list).  This was the highlight of his cruise.   The last day came and the results were in.  Five teams did great, all exceeding the maximum points.  They had all committed to the game.
