This was our 7th cruise. We went with 2 other couples. One had been on the Sun six months earlier and loved it. Apparently, it has gone downhill since then. We spent 1 1/2 hours in line waiting to board. Probably the Corona virus slowed things down because they were checking passports very carefully. Once aboard, we noticed a general lack of attention to detail. One of the couples had written documentation that they had the Free at Sea items, but they didn't show up on their reservation and they spent a long time trying to resolve the problem. The food tasted just o.k. but was only luke warm because service in the dining rooms and specialty restaurants was extremely slow. They were obviously understaffed. It took 3 hours to eat dinner in La Cucina so we missed the entertainment that night. There were a lot of other issues. We got to our cabin and had no deck plans or instructions for using the phone. There was only 1 110 outlet and 2 USB outlets. Not enough these days! The shower was miniscule. At the stop in Cozumel, my husband wasn't feeling well so we stayed in our cabin. He wanted to take a nap. We were on the port side and faced the Norwegian Escape on the other side of the pier. For two hours, they had a DJ on the pier playing EXTREMELY LOUD AND OBNOXIOUS salsa music directly under our balcony. It was awful. I could go on but won't. There were some pros. The ship was clean, the room steward did a good job, we enjoyed the entertainment in the main showroom and in the lounges and disembarkation went smoothly. All in all, we enjoyed ourselves but I am not sure that I would recommend the Norwegian Sun and I don't think I would go on another Norwegian cruise. There are too many other choices out there.
