We did the Wild by Design tour a few years ago and we enjoyed it. We learned a lot about the theming of the park and about the way Disney cares for the animals. We thought it was worthwhile.
Thanks for the link to your report, great photos! Can I ask a question about the walking? The reason I ask is I have a mom with MS. Is the walking pretty fast throughout the trek? She's pretty mobile, but a just a little slow.
