Frequently Asked Questions

Can I choose to stay completely dry while attending S2O Korea?

Due to the advanced engineering and massive scale of the water cannons utilized across the venue, staying completely dry inside the main dance floor area is virtually impossible. The cannons are designed to create a 360-degree soak zone that reaches almost every corner of the audience plaza. However, the outer perimeter features designated food villages and sponsor lounges where water effects are restricted if you need a brief dry break.

What identification do international tourists need to bring to get their wristbands?

To prevent illegal ticket scalping and ensure venue security, all international ticket holders and non-Korean residents must present a valid, original physical passport or a government-issued Alien Registration Card at the gates. Smartphone screenshots, photocopies, or digital images of documents will not be accepted by the security teams under any circumstances.

Are there storage facilities on-site to keep my dry clothing safe?

Yes, the festival site operates extensive, staff-monitored digital locker rental pavilions where visitors can store their dry changes of clothing, travel wallets, and valuables safely for a nominal daily fee. Because these units are available on a first-come, first-served basis, arriving early in the afternoon is highly recommended to secure a locker before peak hours.

What happens to the festival schedule if a summer rainstorm hits the city?

The festival is designed explicitly as an all-weather outdoor water experience, meaning typical summer rain showers will not delay or alter the musical programming. The main stage structures and technical equipment are fully protected. In the rare case of extreme, hazardous weather alerts such as a severe typhoon warning or lightning storms, the organizers will issue safety updates via official social media channels.

Can I bring my own professional camera equipment to record the DJs?

No, professional recording systems, including DSLR cameras, mirrorless bodies with detachable telephoto lenses, long-range zoom gear, heavy tripods, and commercial drone equipment, are strictly prohibited inside the venue boundaries to protect broadcast copyrights. Casual personal smartphone photography using waterproof pouches is fully permitted and encouraged.

How do I purchase food and drinks inside the Seoul Land venue?

The entire festival grounds operate on a strictly cashless payment system to streamline transactions and ensure convenience.
