@Swjosdotschka Thank you for your feed back. I am "planning" on staggering the windows in the habitats so that guests can walk down the lane and view animals on one side only, then move farther down and view more animals on the other side of the lane. This should give the animals more privacy, too. I also tried to allow viewing from more than one direction by having the path in the middle with the train on the outside and the boat ride on the inside. My ideas probably wouldn't work in a real zoo, but maybe I can keep my animal friends content and happy.
