My wife took that tour when we were in Barbados aboard the Dawn Princess two years ago.
The answer to both questions is yes.
The tour went to some great places with great scenery. The guide is a professional Bajan photographer from the island and the tour went several of his favorite places. He was very knowledgable about the history of the island in general as well as the flora and fauna. He readily answered any and all questions regarding photography in general as well as specific questions on technique.
My wife rated the tour very highly.
