The ACC Children's Experience Hall offers groups of ten or more children aged 4–under 14 a 20% discount (₩4,000 per child), and groups of twenty or more a 40% discount (₩3,000 per child). Two adult chaperones per twenty children enter free; extra adults pay ordinary adult admission. Infants under 48 months may enter free with proof of birth date. If an institution needs a preliminary staff site visit, up to two staff can arrange one visit per institution at the Children's Culture Center desk with proof of employment. Other institutional or research-only visits require a prior application and formal letter; unapproved adult-only visits can be refused. Group visitors still need adult accompaniment for children. Check available session capacities and whether separate education activities charge extra.
