We could not give this tour a higher rating! We had the best tour guide who was so professional, knowledgeable, Comfortable & helped to make this the best day. There were 6 adults on our tour…. And I think our only comment was afterward besides “Wow!!! “ was that we all wished it had gone on longer. We boarded back on our ship, and sadly had the rest of the afternoon and evening left over just sitting in port and wished we could have continued our tour longer with David B. That opportunity was not offered to us.. …… but I’d highly recommend you request it!
