Are you reading the CDNN? If so, try to find a more reliable source.
I spent a week diving with Reef Divers and have nothing but praise for the operation. They gave excellent briefings, with detailed information on UW topography, suggested route, maximum depth and maximum time. If you wished, you could follow the DM around or you and your buddy could do your own thing.
That said, I saw a few divers whose level of skills were appalling. In one case, the diver hired a personal DM to literally hold her hand the entire dive. I wouldn't be surprised if some inattentive and unsafe diver got in trouble. It most likely would not be Reef Divers' fault.
If you need someone to hold your hand (and you can't/don't want to pay for your own DM), Little Cayman isn't for you. However, if you want a professional dive operation that gives you all the information and support you need to execute wonderful dives, go for it.
