The cheering, the chicken, the ₩15,000 seats and the honest way for a foreigner to get a ticket. Ten teams, nine stadiums, plus a note on K League football.

An hour out to the big outdoor coasters and safari, or indoors at a subway station in Seoul. Getting there, the paid queue passes, cheaper tickets, and the weeks the school trips take over.

Real prices for transport, food, beds and sights, three daily budgets from ₩60,000, and honest verdicts on the passes — most of the best things here are free or nearly.
