Norwegian Sky receives mixed reviews, with many guests praising the friendly and accommodating staff, enjoyable ports of call, and overall value. However, recurring criticisms include inconsistent food quality, small and outdated cabins, limited entertainment options, and a party-centric atmosphere that may not suit all travelers. The ship is generally considered clean and well-maintained, but some areas could use upgrades. Excursions and specialty services are seen as overpriced by some, and internet connectivity is noted as lacking. Overall, the ship is best suited for adults seeking a short, budget-friendly getaway rather than families or those seeking luxury.
