I have to wonder about those who do not get any response from NCL. I only wrote to them on one occassion but got a response within a few weeks. I did write about concerns I had, but also let them know overall I was satisfied and would sail them again. If letters imply the writer will not sail the line again, all too wordy or filled with nothing but negatives most likely you will not get an answer. Right or wrong, that's the way it is.
