We have done it three times - twice on one trip! Yes, we love it. We'll be going again on our trip in December.
You go on the same basic route as the regular Safari, though you start off backstage, however you pull off the road at various places while they discuss the animals. As with the regular Safari, sometimes you see more animals; it depends on where they are and what they are doing. The guides talk about taking care of the animals and working with them and answer any questions. We really enjoy it and everytime is different because the guides all work with different animals so all have different favorites and knowledge.
We have always gone on the 10am one as that time just works out better for us.
