To put this review in perspective, a lot of my friends said I should be hired by Viking for my rave reviews of their river long boats. About 15 booked cruises with Viking because of them. The Danube Waltz from Budapest to Passau was awesome.
This review is an opinion only. I am interested other opinions as well.
I like to be able to give a fair review with highlights intersperse with occasional constructive criticism where needed. Viking Star Ocean Cruise made this desire almost impossible because the failures are so rampant.
