The current parks are hitting capacity. Non-holiday weekends in spring and summer sell out for both parks multiple days in advance despite being $200 for a basic 1-day ticket. Adding more attractions to the existing two will boost capacity in some ways, but I imagine there are still other logistical bottlenecks limiting how many people a single gate can handle. While I don’t have any sort of estimate of how many people would visit a third gate, the demand definitely seems to exist. Having a separate, third park is better than having two because it 1) has more space for attractions than the speculated DL and DCA expansion plots and 2) should decongest the other two parks which are struggling to handle the current crowd levels. Also, building a third park wouldn’t preclude expanding the other two. Por qué no los dos?
