Norwegian Cruise Line review: Extremely disappointing experience with Norwegian Cruise Line

Norwegian Cruise Line clearly does not seem to care about its customers or the experience they have onboard. My family and friends recently took a seven-day cruise in September, and unfortunately, it turned into one of the worst cruise experiences we have ever had.
Our cabin was located directly above the Luna Theater, and the music and noise from the theater were so loud that it literally sounded as though the entertainment was happening inside our cabin. We called several times to complain and ask for assistance, but the response we received made it seem as though this was the first time anyone had ever complained about the noise.
I specifically asked that someone from the theater come to our cabin and experience the noise for themselves. Instead, we were told that the manager of the theater would be asked to lower the volume. Obviously, I found that hard to believe—were they really going to lower the volume for thousands of guests attending the show because of the location of our cabin?
We were eventually offered the option of moving to another floor. However, that was not a reasonable solution. We booked our cruise months in advance specifically so that our entire family could stay on the same floor. We were traveling with our children and grandchildren, and being close together was important because we were helping take care of our grandchildren.
After returning home, I contacted Norwegian's corporate office and explained the situation. Unfortunately, they refused to offer any compensation or meaningful resolution.
What is most disappointing is not only the noise itself, but the complete lack of concern and customer service afterward. We spent a significant amount of money on this vacation expecting to enjoy a relaxing family cruise, and instead we spent much of our time dealing with excessive noise and trying to get someone to take our concerns seriously.
This was not the level of customer service I expected from Norwegian. Horrible customer service and an extremely disappointing experience. There should be an option for 0 star.
