This was our third Christmas cruise, but our first actually leaving on Christmas Day. Since we left on Christmas, we returned on New Year's Day, which meant this was actually not a "Christmas" cruise to most of the passengers, it was a "New Year's" cruise.
In the past, all of our holiday cruises have been Christmas-themed, since Christmas was in the middle of the cruise. This year, the focus seemed to be New Year's Eve, which I thought was unfortunate, since that was the end of the last evening of the cruise. (Also, New Year's celebrations tend to dissipate quickly - once midnight passes, there is not much else to do.)
This was also our third Norwegian ship - our first cruise was on the Spirit, then the Dawn and this year, the Pearl. All have different personalities, which is a combination of the crew, the passengers and the itinerary.
This was a handicap balcony cabin. When the two beds were joined to make one bed, the alarm button was in the middle of the bed. My wife and I each set it off by bumping into it.
