Magic Kingdom was designed to handle 10 million guests per year, has barely increased its attraction capacity, has unused retail capacity and has even lost dining capacity over the past 30 years. Parks with less visitation, more service and lower prices were able to be profit centers for Disney.Some have said that running the parks at 50% capacity will not generate any revenue for the company. Do we know (roughly) what capacity is the break-even point? Obviously there are many factors to consider in determining costs (immediate, long-term, public perception, etc.), but does anyone have a handle on Disney parks margins?
