I just published a comparative review of 2018 transatlantics - eastward in March on Viking Sky and westward in November aboard Norwegian Star. Here is a link to the whole post: https://cruisinwithclay.com/2019/02/12/transatlantic-battle/
Below are some excerpts in case any of you other Norwegian enthusiasts are considering Viking. I go into a lot (too much?) detail on the actual post including pictures and more examples. I am happy to answer any questions.
