Do not worry if you have booked a cruise on this ship. My husband and I were aboard the Norwegian Dawn, January 10 - 15, 2010 and had a FABULOUS TIME.
Now, Miami was FREEZING - literally. The temperature was below zero degrees celcius...in Miami. As Canadians, we are used to cold and ice and snow...you just don't expect it in MIAMI. But that was the lowest point of our trip...and you cannot blame Norwegian Cruise lines for the weather:)
Embarkation was very easy, as all through the customs building, kind staff direct you to the ship. Check-in was easy and the representative we had was extremely good-natured.
