hi Victor, 
Greetings from Malaysia. My wife and I enjoyed our stay in Jeju and later Seoul. It could have been better if not for the rain on the first day. We also felt that it could be better if you consider giving more time for the group members to take photos and enjoy the scenery, rather than catching up with you. We almost lost you at Hallim park because we spent some time taking photos at some locations. 
On a postive note, the choice of accomodation and it's location was good, hotel room was nice and cosy. Hope to go there again in the near future. 

Thanks.
