The Dawn definitely met our expectations, and I would highly recommend NCL and the Norwegian Dawn. This was my 10th cruise and my fiance's first. We had a great time and would take this ship again. The highlights were Bermuda, the ship itself (beautiful!) and the crew.
Embarkation was decent - fairly well organized but we did end up in a line. Total time about an hour from the time we got to the pier to the time we boarded the ship.
One engine was broken, so we got to Nassau very late and didn't get off the ship. They offered us a $50 shipboard credit. Not a big deal to us, but I did feel badly for those who had planned activities in the Bahamas.
