Go over to the cruise line section of this board to Norwegian. There is a post about 10 lines down that reads "Is NCL and the Wind as bad as everyone says". Don't let the title to the post scare you as the answer is that it is quite fine. Go to my first reply in that post and you will find a nice summary of suggestions on what to do on this cruise.
We had a wonderful time and did not hear a single negative thought from other passengers.
Happy cruising /you are headed for paradise
