Been having a few problems where I wanted to connect some parts of my parks via monorail, but always forced to connect with road, but doesn't allow me to just have monorail, like in previous tycoons, as long as some kind of transportation was connected to rides or stores, you didn't always need roads. Most notably Isla Sorna, I wanted to keep the open landscape feature from the start, and have all the dinosaurs run freely without any enclosures and viewing exclusively through gyro spheres, and the guests move around via the monorail with some walled off spots for stores and hotels, but cant have that when you have to connect everything with road, because you either allow the Spinosaurus to run around eating guests or you wall everything off.
