An enjoyable way to spend an afternoon. John, the tour guide was entertaining and knowledgeable. The girls were very attentive. There is so much to learn about the sites and seeing them from the water adds an entirely new perspective. The fog rolled in quickly while we were out, but it added to the mystery of the sites and we were close enough to shore to still see them as we passed by. The length of the cruise was perfect...not too short, not too long. I would recommend it if you have the time while visiting.
