What is the best way to keep your park from overcrowding without your guests getting confused and angry because of too many sidewalks in the video game Roller Coaster Tycoon Corkscrew Follies?

It isn't usually too many sidewalks that confuses them and makes them angry.... it is sidewalks that go in circles, and areas where 4 sidewalk segments are together. One way to avoid these problems is to use directional signs. If you mark some places "Do Not Enter" and avoid making the ONLY sidewalk that way, it limits congestion, and helps people know where to go. Also, when you get the message that people can't find their way to the exit, you could add information booths with cheap maps in that area, or you could actually pick the people up and move them to the exit, even though that is high maintenance. :) Some of the pre-built parks, or parts of parks have HORRIBLE sidewalks, and you should fix them before you let people into those areas. I agree with the above answer. Another way is to make chairlifts, or monorails that go by the entrance to your park. A good thing to do is on any ride if the exit path is long then put a "Do Not Enter" sign.
