We have been on 3 previous cruises with princess so this was our first on NCL. We are a couple in our 50's and were very disappointed in the trip. I will say that embarkation went smoothly and we liked our balcony as it was the only relaxing place we found on the ship.
The bed was super hard but sleeping was impossible anyhow since unsupervised children were running up and down the hall yelling and screaming until past 1 am. Adults as well frequently walked down the hall talking loudly and laughing.
Food at the buffet was dreadful. We ate at one specialty restaurant and could not understand why they charged extra as the food was only marginally better than in the other restaurants. My husband was served undercooked scallops I had a creme brulee that was quite watery.
