Leaving the park

We´ll visit Magic Kingdom for the first time in February. When do we need to leave the park? It says opening is from 09-08 but then there is a show at 08…

Most likely the hours will change between now and then but if the hours stay the same - you can stay for the show- walk through some stores- sit on a bench- wait for the “kiss goodnight” on the castle. I would say 9:30-10:00?

Thank you!!
