I think they should let us build parking lots, bus loops, monorail stations, boat docks, etc, outside the park. And we could maybe have a highway with a road coming off to the parking lot. It'd be cool to see cars in the distance and cars and buses coming in and out of your parking lot, but that should all be an optional detail to be later added; however, it still is an important detail because right now, the park entrances don't feel very realistic.
