In seeing screenshots and videos of other peoples parks, they are very close together to maximise coin production. My park is very different though. I like to pretend that there are visitors in the park and make roads for supply lines to the dinosaurs.
The part where the train halts, is where I think the people come in. That is where my road starts to take the people to the triple crown hotels.
There is also another road for park staff to feed the dinosaurs on that side.
The empty spaces are where people will walk to look at the dinosaurs.
There is a road to go to the raptor paddock too.
So, this is very different from other peoples parks
