Can someone tell me what exactly is drift snorkeling and how it might differ from the Jolly pirates trip.
Much like drift diving, they drop you off at one spot and pick you up at another. This is done because most people would be unable to swing against the current back to the original drop off point. It also allows you to cover far more area without expending more energy. It sounds like they escort you with a smaller craft, so there isn't any danger.
