This was our second Christmas cruise with Norwegian Cruise Lines; both times out of Port Canaveral. And, before I go any further, I have to recommend Cape Canaveral, Cocoa Beach and Kennedy Space Center to visitors for excursions. Not that we took any...but we live in Cocoa Beach and are very proud of our area.
We are proud of Port Canaveral, too, although it IS having some growing pains. We embarked from the recently upgraded Cruise Terminal 10 and, personally, had no problems. Of course, we opted for an early arrival time (10 AM) and were able to have relatives drop us off. Later arrivals complained of long wait times in the hot Florida sun. There is also a traffic flow issue in and out of that end of the port, where the access road involves a drawbridge which can be open at inopportune times. The signage can be a little confusing, too, especially since Disney and Carnival also dock at that end of the port.
If you are not coming in on a Norwegian-booked flight/shuttle from the Orlando airport we recommend making sure you get an early boarding time and plan to eat lunch on board.
