no it's not. it's the closest to where we are staying (geoje island)  . it's about 3 hr drive to seoul.

september still hot. end of sep, slightly better but still quite warm. go on oct better la at least can see the changes of autumn foliage

i was there from end aug till mid sept last year. weather was so so fine. sunny but cool, so not a single drop of sweat 

have conference in KINTEX?  go scroll the lake park. you can check out the musical fountain show at night during summer..
yeah you are right. take your time to explore nearby area la.. go the mall wash eyes as you mentioned earlier. stuffs there slightly cheaper compare to the city  .  cause after your conference you will be travel back to the city right?   
bought your flight ticket? usually holiday season not cheap

i just got back from Seoul...
if you want to change your currency, at the Incheon airport got 1 money changer that sell Korean Won cheaper than Malaysia..

under which telco? last time i rented under kt olleh..very good service and coverage.

where got 39.80 that high la.. you are looking at japanese yen it's. you mention yen btw, won only around 36. previously less than 30.
my friend rent before she no comment anything la.. so i guess should be ok    i plan to give it a try for my coming trip
