I rarely write reviews, but I believe that this may prove useful to those considering NCL.
We have cruised on most of the lines - 4,5 and 6 star. Many comments regarding NCL have been warnings not to cruise with them for various reasons.
However, as we are in Spain for the winter and NCL is the only cruiseline cruising from Malaga, we thought we would give it a go. The price was VERY reasonable and we had a balcony cabin which was fairly standard.
