I have not dove in the Bahamas but have been researching recently.
There is a place in Lantana, Fla. that motors over to Bimini on a Friday morning, YOu dive that afternoon and Saturday morning and Sunday morning and motor back Sunday afternoon. You stay in a house with other guest on the boat and all meals are prepared for you. $500pp This trip does not run every week as the owners (DM and boat captain) have normal jobs and do this about once a month I think. Mermaid divers. I hope to do this sometime this year. Just a thought
