The tour guide was friendly and informative. But he was 15 minutes late to pick us up he said it was due to traffic. As a result, our 3 hour tour was shortened by 15 minutes. Rather than extending the tour to provide the full 3 hours he cancelled the last stop on the tour! Because it was not our fault he was late, the tour should have been extended to allow the full itinerary. Also the guide did not have a business card or other identifying information. The van was unmarked. Therefore, we were never sure that the tour was provided by a bona fide tour company.
