I understand. Who wouldn't want to get close to the animals. My walkthrough paths do get a lot of foot traffic, but it doesn't look as crowded as yours, so maybe the animal is the factor, or the space the habitat takes up and thus the path sizing.
The difference between these walkthrough habitats of mine appear to be size and type. The Porcupine (1) is a fully interactive walkthrough with the scattering of guests turned off to keep them on the pathing. The Peafowl (2) is half the size of the Quokka (3) and could explain why the Quokka looks the less crowded if space and interactivity are factors and not just how
interesting the animals are. Also throw in the total guest count for the zoo and it might well increase the count in particular habitat areas whether walkthrough or not, just more in walkthroughs.
I see yours is a tortoise habitat, I did try that before, but it did get too crowded and stressed out the animals too much so I took out the walkthrough portion of it. I suspect the huge number of babies being babies for a long time makes them more interesting. I almost always use one way glass barriers for shy animals now. My current Madagascar zoo with Flamingos as a short wall habitat are having stress issues as well due to their popularity, so having to put in ton of blocking bushes in key areas to give them areas to hide in.
