We have just returned from our cruise of the Hawaiian Islands on POA. Overall we were very satisfied with our cruise experience - this was our 4th cruise, but the first on a Norwegian Line ship.
I read some negative views before we left about the quality of the service, the size of the cabins & the food. However, we found the service was comparable with other cruises we've been on - our room steward in particular was very good. The food was fine - we didn't go to any of the speciality restaurants ( I figure we've paid for our meals in our fare!!). The entertainment was excellent. We had an inside cabin and it was comparable in size to others we have stayed in.
I attended the Meet & Greet and there were several crew members there to meet and talk to us. That has never happened on our previous cruises. We were given their names and extension numbers and invited to call them anytime. (Not sure if anyone took them up on it!)
