Update on this post.
We cruised the breakaway, from NYC to Bermuda in October.
Pros -
The haven was amazing, I don't think we would cruise Norwegian again, if we did not book the haven.
The haven pool area and outdoor seating area were quiet and relaxing, with great service.
The flexible dining was great, we enjoyed the steak house, seafood restaurant, and Italian restaurant
Exiting the ship at the end of the cruise was very easy, we were escorted to the customs area. If you stay on the haven level, take advantage of the breakfast on the final day.
Cons -
Butler service was not really noticeable, this may be a result of being aft, on the ship, away from the main haven area.
Smoke mid-ship was bad, especially near the casinos.
Service was not the level we experience on the Disney cruises.
