Most car rental companies at Incheon Airport only have a few car seats in inventory. If you didn't reserve one in advance, there's a real chance they're out — and you can't legally drive off with a toddler in your lap. One Taiwanese family hit exactly this wall at pickup. They found KPLANZ, grabbed a car seat in Hongdae, and got back on the road the same day. DM @kplanz.official. Pack less, care more.
