Where to Wait Before the Show#

September in Korea can still be quite warm and humid. Since KINTEX Exhibition Center 2 has fully air-conditioned indoor lobby spaces, it is best to stay indoors to avoid the heat.

Hyundai Department Store (KINTEX Branch): Located just behind KINTEX Exhibition Center 1. It is a 12～15 minute walk from Center 2, offering a vast array of cafes, restaurants, and a comfortable, air-conditioned indoor environment.
Exhibition Center 2 Cafes: There are several franchise cafes and food stalls located on the 1st and 2nd floors of the lobby.

Restrooms, Convenience Stores, and Lockers#

Tips on managing your luggage and locating essential facilities so you can enjoy the concert without worry.

Digital Lockers: Lockers are available in the 2nd-floor central lobby and near Hall 6 and Hall 10.
- Locker Fees: Small: 1,000 KRW / Medium: 2,000 KRW / Large: 3,000 KRW
- Payment Methods: Credit cards, Samsung Pay, and T-money are supported.
- Locker Tip: Since many concertgoers will carry bags, lockers are highly likely to be filled by noon. If they are full, use the smart locker station (Keep24 Daehwa Station Exit 4, etc.) located near Daehwa Station Exit 4.
Restrooms: Restrooms are located near every exhibition hall entrance and lobby floor in Exhibition Center 2. Lines get extremely long right before the show, so consider using the restrooms on the 2nd floor or inside the department store beforehand.
Convenience Stores: Large convenience stores are located on the 1st floor of Exhibition Center 2 and near the central passage. We suggest purchasing bottled water before entering the standing zone.

How to Head Back After the Show#

The concert is expected to end around 20:00 to 20:30. Given that over 10,000 people will leave simultaneously, planning your return route in advance is critical.

Returning via GTX-A KINTEX Station: This is the fastest way back to Seoul. However, to prevent overcrowding, station staff may restrict entry to the platforms temporarily. Be sure to check the last train schedule in advance.
Detour via Subway Line 3 (Daehwa Station): Daehwa Station is a 20-minute walk from Center 2. If the GTX-A KINTEX Station entrance has long queues due to safety control, walking slowly toward Daehwa Station or Juyeop Station (주엽역) to take Subway Line 3 is a smart way to avoid the crowd.

Tips for International Visitors#

Get a T-money Card: Make sure to purchase and top up a T-money transit card at an airport convenience store or subway station before traveling. It is required for all buses and subways.
Verify Station Names: Match the English names on the subway screen doors (e.g., Daehwa Station, KINTEX Station) to ensure you do not miss your stop.
Passport Required: International ticket holders must bring their physical passport or alien registration card (ARC) along with their ticket reservation page to verify identity at the ticket box. Mobile screenshots are typically not accepted.
