Seosan City's fee page lists 4D cinema admission separately from the Birdland main exhibit. 4D tickets cost ₩2,000 adults and ₩1,000 teens/military; eligible Seosan residents pay ₩1,000 / ₩500. Children 12 and under are free. The ordinary Birdland entry fee is ₩3,000 adults, ₩2,000 youths, children free, so do not assume a general ticket already includes the 4D film.
