Well, I got to this thread late. I also do NOT understand how Viking Ocean got rated #1.
First, we sailed the Mars from Bali to Sydney when it was a brand new ship. To be fair, we feel it was one of the most well designed ships and a joy to walk around and enjoy. The cruise director was one of the best we have ever seen, bar none.
However, our dealings with Viking started about a year ahead when their requirements were: Pay now, in full, no exceptions. Sort of different from all other cruise lines we sailed on, but OK, done.
Next, Indonesia had some pre-arrival Covid app that absolutely did not work. Viking response did not offer any help or suggestions, just "do it", even though it did not work for us or our other friends we went with. Indonesia (I think) finally just gave up and never checked our compliance on our arrival. No help from Viking.
I understand the concept of Chef's Table ... what the chef designs for the evening is what you get. Not Viking's fault, but I have shrimp allergy. At the restaurant; ok no substitutions, we will take the shrimp off, you can have the underlying lettuce base. Similar (but less stringent) treatment at other dining venues.
Lastly, disembarkation in Sydney was at some boonie docks maybe 5 miles out of the city. Find your own way to your hotel. The final insult was, the next morning, seeing the Viking Mars docked at the Sydney Circular Quay ready for the new passengers.
I think we are just not used to the Nordic attitude. Here it is, what you see is what you get, and normally quite decent and good. It's just how it is presented. We're Regent loyalists and used to being coddled a bit more.
