It seems to me that the reviews of this ship are one end of the spectrum or the other. I thought I would add my two cents to the mix..
Background - This was my 27th cruise. 12 have been on NCL, most of the others on RCI, and have done a few on Princess, Carnival and Celebrity as well.
Embarkation: This was a bit slower than we have experienced in the past, but I believe due to the fact that they had a hard time getting the previous week's guests off the ship! One of the NCL reps told me they were literally calling people by name coming out in their bathing suits. LOL, some people apparently aren't ready to let it end...
Great cabin location. Elevators were hard to get, but we walked the stairs most of the time. My parents were in 11317 aft cabin and had terrible vibration and it was loud from the sound of the ocean below and with the flat back of the ship was also hotter as there was little to no breeze on their balcony. Ours was definitely a more prime location.
