Norwegian Sky receives mixed reviews, with many guests praising the friendly and attentive staff, enjoyable ports of call, and overall value. However, there are recurring criticisms regarding the quality and variety of food, small and sometimes outdated cabins, and limited entertainment options. The ship is often described as better suited for adults or short getaways rather than family vacations. Cleanliness and ship maintenance are generally positive, but some guests experienced issues with air conditioning and room odors. Pricing is considered fair, especially with included perks like open bar, but some feel that extras and excursions are overpriced.
