28,322 nautical miles on Oceania’s Insignia – more than the Earth’s circumference. Fifty-three ports-of-call and three overland tours. Twenty-five countries visited in 112 days away from home. Weight gained: Cathy zero, Doug one kg (remarkable, given the number of desserts consumed). During our final week the Panama Canal was transited, and we toured the old colonial city of Cartagena by Segway. Our captain altered course twice, once to skirt a tropical wave and then for a dramatic night-time rescue at sea. The sea settled in time for a flurry of packing and sad farewells as we approached our disembarkation port, Miami.
