Plan on a few total rebuilds of your park as you become more experienced with the game. Nothing placed inside your park is permanently anchored to the spot where it’s built. Placing buildings costs coins, but moving them is free. Paths and fences must be erased, but they’re always free to build. You don’t need to use the Park Editor to modify your park, but it removes all the distracting peeps and makes it easier to see how much space each building requires.
