ss it depends on point of view. My brother-in-law and his father just returned from the Alaska on the NCL Sky (I assume it was the same cruise). He is a veteran of 23 cruises, and his father has been on 27. They both ranked this cruise as a top 5, and as far as value for the dollar is concerned, my brother-in-law put it in the top 2.
I should say that they both love Freestyle, and would choose it over traditional. I like both, but most older cruisers I've interviewed prefer the traditional style. Freestyle seems to appeal more to a younger crowd and those cruising with kids.
