You are most welcome. They didn't use to charge for snorkeling there. Abanks rents lockers and equipment if you wanted to do that.
Here is another link. I go there every time I'm on Grand Cayman. I first went there out of curiosity because Abanks diving was featured in the John Grisham book and movie The Firm. I fell in love with the place and the conch fritters. You can see the place from the ship as they will be flying a "Diver Down" flag over the building.
