For F! all the River of America attractions close in the evening, ie, SS Columbia, Tom Sawyer Island. With early sunset and long hours when there is one F! The Mark Twain can restart after the show but this is rare.
For Fireworks about an hour before the rides within the walls of the Castle Close, they reopen about 30 minutes after with a rope drop where everyone mostly rushes to Pan and Mr Toad. These closed attractions include the Carousel, Peter Pan Pinochio and thier neighbors. Mad Tea Party and the Storybook Canal that are outside the Castle Walls stay open.
For WoC, often an hour to 12 minutes before, so the people already in line can ride before WoC starts a handful of Paradise Pier attractions close. TSMM, GSS and LM stay open. On occasions when WoC runs early and the park is open late CS can reopen, this is rare.
