Taina is a beautiful system, but it has tricky parts. The halocline can be very disorienting, depending on water levels, you might be in it for a while. The cave has deeper areas, and with the air mix and haloclines, and side tunnels that can be small and silty, I can definitely see it being more dangerous than other guided cave dives.
I think if they made people carry their own tanks down the stairs, that alone would cut down on the number of OW divers diving there. :D
