But allow yourselves at least an hour to exit the show afterwards and get out of the park. You spend more time doing this than at the shows at Disney. My approach is to just sit tight. I have learnt to ignore the exit for half an hour or so and then leave in a civil fashion
When are you going? It varies according to the seasons and predicted crowd levels. You can find them on most of the park hours websites but you usually have to select fireworks and events to see this on a separate page.
