Had the pleasure of a 1 on 1 tour with Mr Duffy on Friday afternoon. The tour took about 45 minutes. We left on time at noon and returned to the starting point at 12:45. He is very informative - explained the history of the French Quarter, the different architectural styles and what to look for when walking through the quarter. I wish the tour would have been a little longer - and covered the Mississippi River and how that helped form New Orleans, a litte more detail in Jackson Square. Overall, I would encourage visitors to seek out his tour.
