In sequence the voyage takes in England (Southampton), Spain (Cartagena), Sardinia (Cagliari), Greece (Corfu), Croatia (Dubrovnik, Zadar, Split), Sicily (Messina) and 2 more.
Because it's round-trip from Southampton, you fly into and out of a single city and unpack just once. Longer hops are crossed on the 11 days at sea, keeping daylight hours for the ports.
