If you have small children, it makes sense to leave the park right after the fireworks show, which is probably already way past their usual bedtimes. Unfortunately, everyone else has the same idea, and leaving the park with a herd of people (especially if you were viewing the fireworks from the back of the park) can be a superlengthy and annoying experience. A workaround: make sure you get a fireworks viewing spot up front, closer to the exit, or force yourself to stay for an extra ride or two until the majority of the crowds clear out.
