The World Cruise sails from L/A to Greenwich in London, so it completely misses Northern Europe. Neither Judi or I have visited Norway before, so were interest where Viking would take the Nepture after the World Cruise.
Bonus – she is doing a 29-day cruise around UK, across to Norway and then the Baltic. Wow, 3 great itineraries rolled into a single cruise. Therefore, we booked this additional cruise, so will be flying home from Copenhagen.
