Victor, 

How have you been ? I am Jeong who joined your tour with Ann, Ji-hee very early this year. 
I just came back Korea last week from Philippines 
I am only writing it in English because there is no Korean language on my computer in the office. 
(Actually, I am writing memo during my working hours, I hope my boss doesn't know it !! ) 

Last weekend, I saw the pictures which we took together and remembered great time on Jeju. 
I belive this tour became big value ONLY with your knowledge. 
Also, your tour is different from the other packages which focuse on the own profit. 

One more, thanks for a number of mandarin orange for free.... 

Have a good day. 
Jeong Hwang
