Seoul is one of the largest cities on Earth and as such has parties happening almost everyday. As a Yonsei student you will be given several opportunities for free admission to clubs and also chances to interact with club promoters to run the city. Here are some of the top clubbing promotion networks I encountered while in Seoul:
Krome Entertainment: Organized in 2010 and also constantly planning parties all around Seoul
Sky Events: Social Korea Youth, connecting students from all the Universities in Seoul
Students Gathering in Korea: Promoted 2 School Uniform parties in Hongdae, among other parties
Watz Up Korea: Consistently planning parties around town, including the first Caribbean club nights and basketball-themed parties
