Overall i like the Viking ocean ships. Clean, crisp norweigian style. Food choices good. Room layout very good. But this review is about my view of the way Viking handled the itinerary debacle caused by the virus.
We were merrily headed to Hobart Tasmania when the captain informed us early in the morning while at sea that we were headed on a beeline to the mainland of AUS to get into port there. It was obvious from the direction of the boat that Sydney was the intended port. NZ had just closed its ports and it was clear AUS would follow suit. We never made it to Sydney. AUS closed its ports before we got there. We were redirected to Melbourne. Due to an AUS exception to its port closure order we were able to disembark as long as we all headed to the airport for departure. To my knowledge nobody on board was ill before disembarkation.
Overall I was impressed with Viking's offer for free flights home for everyone on board even if you did not arrange travel thru Viking. Coach of course. It probably took a huge effort to get flight's (re)arranged in the short time before disembarkation for those who did not do their own thing. My wife and I immediately redid our own arrangements so we could stay in business class. Viking provided transfers for everyone to the airport and allowed people to stay on the boat as long as possible before their flight.
