I know when I was younger and went to Disney in Paris that they still had parades in the themed zones like an hour before closing. So I can believe that.
Fireworks at most amusement parks, but especially Disney, just gather everyone outside of restaurants and gifts shops, so those can try to start closing up while the fireworks are happening. Fireworks end, everything is closed, everyone takes the hint to use the restroom one last time and GTFO.
Places like Disney do the opposite. Fireworks are late so people stay and spend more money on food, drinks, and extras.
