Korean International Summer Schools - Yonsei or Hanyang or SKKU

Hello,

My university allows us to do short term study abroad opportunities, and I'm trying to toss up between Hanyang summer school or Yonsei summer school. Not so worried about subjects, but I have never been to Korea before and I won't be going with anyone else so I am more wondering about which program is easier to make friends/ have the best experience and less so much in the prestige of the place as a 20 year old from Australia. From what I have gained so far, Yonsei's courses are a bit more interesting but Hanyang offers quite a lot more outside of class activities and a trip to Jeju for the fourth week.

if anyone has any experiences that they can share that'd be great. Thanks.
