We (my party of 4 adults) were very disappointed as the description of this tour was not what was delivered by the guide Yvonne. Before we even started the tour she changed her plans to accomadate one person who wanted a bottle of water-really!
20 or so people who paid for this tour had to accomadate one person who was not even gracious even to give a thank you. So our tour drove to the visitor centre, where the person could get water and then our guide decided to talk to us for over 20 minutes about Hurricane Catrina- really, this was not in the tour description and if it was we would have booked a another tour!
A lot of the information in this tour was repeated in other tours, be careful in planning not to overlap. Otherwise very good tour and guide.
Informative tour, left on time, done in about 1.5 hrs. Our guide was ill so wasnt very engaging, but i suppose when trying to keep a tour on track you can't let questions and random discussions take over the tour for everyone. I have always wanted to do this tour and wasn't disappointed in what I learned. Worth doing.
