My wife and I are leaving on the Dawn 4/21/13 for a 12 day Tampa - Boston. We will update you on the ship when we return. This is our 5th cruise, 2nd on Norwegian. Our experience is Norweigan has the best shows / entertainment, and good food 2nd to Royal Caribbean.
I was on the Dawn a few years back, and the staff and crew are as good as they get; the ship is in really good shape; maybe not as many bells and whistles and many current ships, but this one is just fine and you should experience a wonderful cruise.
We did the Dawn a few years ago and were quite pleased. Above average entertainment, good food, and pleasant, efficient service. I am no a fan of all of the extra fee restaurants. Did not think that the food was any better than in the free MDR. Breakfast buffet was far superior to anything we had ever experienced on any line.
