We went to Nochi Com (or however you spell it). For our group of 9- there were 4 adults and 5 children, we were able to get one cab for $34 each way. We gave $40 to include the tip. There is a huge pool and "hot tub" (that wasn't very hot). Also a swim up bar. All drinks are included, including virgin iced drinks for the kids, which they loved, since they cost on the ship, we let them drink them all day there. Alcohol is also included and it was funny that sometimes the drinks seemed watered down and sometimes they really packed a punch! I guess it depended on who made them! There is the beach and the ocean available for free. There is a guy that comes around and tries to get you to go snorkeling or on the glass bottomed boat- but that is all for a fee.
To be honest, after the hectic time on the ship, our group LOVED the relaxed time on the beach. They splashed and played. We brought our own snorkeling stuff and while it is true that there isn't a reef, if you swim out far enough, there are some fish to look at, and the swim is really easy. My 9 year olds were able to easily swim out. There are also LOTS of sand dollars on the ocean floor so my 9 year olds thought it was great fun to dive down and get them. They are really fragile though and most broke.
So, my input is that it is great, but if you are looking for a busy day, it probably isn't the best. It was perfect for us.
