I had an average experience with Aquacenter Diving. It's not that anything was bad, It is mostly that the staff was just so-so in terms of being friendly/helpful. Nothing BAD at all, mind you.... but in Costa RIca, the people are all extremely friendly and nice and helpful. So, the British staff on our boat was just..... "meh" compared to the locals who are amazingly friendly. And since the viz was only so-so (not their fault), it made the dive kind of "meh". They did offer us juice and fruit and cookies during the SI between dives, so that was a nice touch. They did everything they were supposed to do... if you don't care about engaging with the crew on your dive boat and underwater.... your experience won't be altered. But if youa re looking for a fun, great crew to take you out, I might look elsewhere. I would dive with them again if I did some comparison and it seemed the same everywhere.... but next time I come to Costa Rica, I will probably see if there is another Dive Outfitter to try. Nothing wrong with them, just.... average.
