Yes, you can typically ride attractions after the Fantasmic! show, but it depends on the specific park's closing time and the show's schedule for that night. At Disney's Hollywood Studios (where Fantasmic! is held in Florida), the first show usually ends about 30 to 45 minutes before the park officially closes. If the park is still open, you can head directly to nearby rides like The Twilight Zone Tower of Terror or Rock 'n' Roller Coaster; as long as you are in the queue one minute before the official park closing time, you will be allowed to ride. At Disneyland Park in California, Fantasmic! often has two showings; if you attend the first show, the park remains open for several more hours, allowing you to ride attractions in New Orleans Square or Galaxy's Edge. On nights with a "second" show that ends at or after park closing, most rides will have already closed their lines. A popular strategy is to visit popular rides during the show when wait times are often at their lowest, or to use the final 20 minutes after the show to squeeze in one last high-demand attraction before the gates are locked.
