We just returned from the 10 day sailing of the Norwegian Sun (November 25 -- December 5). I'll write my review and try to be objective although it would be difficult for me to find much to criticize on The Sun. This was our 4th cruise (2nd with NCL) and by FAR the best we have been on. We loved every minute of it. Most of my review will be about The Sun rather than the ports -- we cruise for and enjoy the actual cruise the most. The ports are nice extras for us, but we love the ship and actually 'cruising'. We didn't do any excursions and just went around on our own for a bit at each port.
This will be a longish review so if it is too long -- the short version is that we would HIGHLY recommend The Sun and NCL. The crew, cruise director, cruise director staff, entertainment and officers were all wonderful -- the best we have sailed with. As before, we loved freestyle cruising.
We are in our mid/late 30s. Being a 10 day sailing out of Florida, most of the passengers were somewhat older than us. We enjoyed this and enjoyed talking with many of the passengers and it was a very relaxing cruise. Our first 2 cruises were 7 or 8 day cruises. Last year we took a 10 day and that is our preference. I find that (for us) -- on the last couple days of a cruise we are sad that it is almost over, so we truly enjoy more days on a longer cruise than a shorter one! I don't know if the ship was sold out, but it never really felt crowded anywhere (except for maybe the buffet!).
