There are 2 major theme parks(놀이공원) in Korea.
The best one is “EVERLAND(에버랜드)” and the other one is “LOTTE WORLD(롯데월드)”.
Lotte world may be more popular to foreigners due to its accessibility from Gangnam(강남).
Nevertheless the biggest one is Everland. It’s famous not only because of their attraction but also their amusing staffs.
Here is an example and you can find many other videos in YouTube.
