I have clients who will be in SP in January and want to get their Open Water Certification. The hotel they will be staying at (Caribbean Villas) recommended Belize Diving Adventures. I have not worked with them before. What do any of you divers out there think about this company? Any personal experience? I am not a diver but I usually recommend Elbert, Amigos del Mar, Ramon's, Hugh Parkey's & Ecologic to my clients, and I normally don't pre-book diving, but have to in this case.
