Hi, I would like to ask do I need to wait until the KT Kumho office to open only can return the car? Let say if my flight is at 9.30am back to Seoul, would it be too rush to return the car? Thanks in advance!

yeah lah.. heard that it will continue to fall due to oil market falls 
yeah. either change Won in Msia or bring your balance USD/SG dollars to Korea to exchange. no point you change back SG dollars to RM and from RM to Won. more rugi..

aiya.. i will be around beginning of Apr.. can't meet u up    u go 1st week of mar, you wanna go ski?? hehe

which hongdae station? metro or the airport rail?
yeah still have

exit to metro quite crowded lor.. and if you stay in hongdae main area very noisy and crowded. usually people will stay around quiet side at donggyoro, worldcupbukro, yeonhuiro, sinchonro, dongmakro, etc.. btw, it's up to you and your friends also hehe.. too many choices of guesthouse.. hard to list out unless you specify your requirement of what types of guesthouse you prefer
