The framework is FAMILY ENTITLEMENT GATE. Before looking for the cheapest platform, align five things: child age, admission category, whether the child will use the free traffic experience, whether an eligible driving guardian is present, and whether your platform can actually deliver a usable voucher.
30-second decision
- Child under 36 months: do not automatically add a child ticket. Bring age proof and recheck the current free-entry rule.
- The children's traffic experience is the reason for going: the current source describes it as a free experience, but it requires a guardian who can drive and remains subject to on-site operation.
- You do not have a Korean 010 number: Klook's current delivery route can be the deciding constraint, because the usable ticket is sent through a Korean 010-linked KakaoTalk/SMS channel rather than the Klook voucher itself.
- You arrive late: the source records 09:00–18:00 operation with 17:20 last entry. Usable visit time matters more than a small discount.
Adult ticket price is not the family total
The source separates adult, student and child categories, with the child definition starting at 36 months. That means families with infants should not simply multiply the visible child price by headcount. Age proof is part of the transaction when a free category matters.
The children's traffic experience is not a separate paid add-on
The museum currently presents the children's traffic activity as a free experience that requires an accompanying guardian who can drive. Do not inflate an OTA package because it mentions the experience as if it were a paid extra. At the same time, do not treat it as guaranteed at any exact time; on-site operation still matters.
Voucher delivery can eliminate a platform before price comparison
Klook product 1981 currently uses a Korean 010 phone number to deliver the usable ticket through KakaoTalk or SMS, and the Klook voucher itself is not the admission instrument. KKday product 39816 uses an e-voucher/barcode route instead. Those are different transaction products even when both are called admission tickets.
Compare only normalized ticket contracts
Use the same visit date, traveller ages, ticket class, eligibility, cancellation and included experience. Then compare the final payable total.

Verdict
Families should decide eligibility and delivery first, price second. If the child traffic experience is important, verify the child's age and guardian condition. If you cannot receive the Klook ticket through the required 010 route, remove it before comparing prices. Once every platform describes the same usable admission product, the final-total comparison becomes straightforward.
