[Sunday Roundup] Four Thresholds on Day One: Payments, Transport, Reservations, Nights

This Sunday roundup follows the four options in this week's reader poll, 'Ask Korea This Week.' First, payments: cards are widely accepted in Korea, but traditional markets, street stalls and some small restaurants still require cash, and topping up a T-money transit card is easiest with cash. Second, transport: from Incheon Airport, the airport railroad and limousine buses are the standard routes into Seoul, and a single T-money card covers subways, buses and even convenience stores. For intercity travel, book KTX seats in advance via the Korail app or website.

Third, reservations: popular shows, palace night programs and famous restaurants often require advance booking, so check official channels before you go. Fourth, nights: for any trouble, the 24-hour multilingual travel helpline 1330 is the fastest resource; in emergencies dial 112 (police) or 119 (fire/ambulance). Late at night, check public transit closing times and use taxis after hours. This week's poll is open - next week our desk will report the answer to the most-asked question.
