Hi! I was there on one of the 3 day inaugural cruises. It is a huge area and you can for sure get away from the music. We chose to sit on the beach right behind where it was being played and I did not think it was bad. It certainly isn't my kind of music but it was not offensive.
The entire area is very nice. It is spread out and there are a ton of chairs and umbrellas on the beach and by the pool. It was much easier to get a drink at one of the bars than on other parts of the island. There was a line at the Snack Shack but it went very quickly.
That being said, there are so many free places on Coco Cay that are equally as nice. I'm not sure that it is necessary to spend money to go to this beach. But...we had a great day there!!!
