We chose this cruise largely because of the southern Caribbean itinerary, the ports (a couple of which we had not visited previously), only one sea day, and the fact that we have sailed on Norwegian four times prior and have thoroughly enjoyed it.
The embarkation process in San Juan was really quick and easy and we were on board in less than 20 minutes. The lifeboat drill occurred literally as we walked on, which was somewhat annoying after a long travel day (we wanted a drink!), but in hindsight, it was nice to get that box checked right away and to get our vacation started.
We booked late so balcony was unavailable, but our picture window cabin on Deck 5 was perfectly fine. It turned out to be a good location to get around the ship but also was really close to the gangway on port days which was great. We spend very little time in our cabin, so we dont spend a lot of time critiquing that part of the trip.
Cabin had a great location for our needs (close to gangway in particular) and was in a pretty quiet part of the ship. We usually like a balcony, but the picture window category was fine. Down pretty low, so felt little motion of the ship. Cabin Steward (Liu) was great - unobtrusive, but awesome service as needed.
