If anyone is debating between Norwegian Cruise Line and another cruise line. I strongly suggest Norwegian.
I have been on the Dawn, and am already planning a second. I have also been on a Royal Caribbean and Blue Cruise Turkey, so I have a bit of experience with cruises.
The reason I recommend Norwegian so strongly is because of the personal experience I received and how everyone on the cruise is extremely helpful. Even if they are on their break they will do everything to make your experience more enjoyable. They also encourage you to participate in the many activities on the ship, and include everyone in the parties on deck.
The service and room itself was amazing, it was always ready before we came in and they would always leave a nice treat for us each night and morning.
