The great thing about going to a travel agent in Iteawon is they actually know what travel insurence is. As foreigners we're not allowed to buy the travel insurence at the airport
Out of curiosity, why do you buy travel insurance? It's never crossed my mind.
Itaewon is quite far for me, not living in Seoul. I contacted Kangsan Travel
both by e-mail and by phone and they spoke English fluently. They were slow to come up with flight options and a bit expensive, I thought, so I didn't buy tickets from them, but there were no communication problems in English. They are in Busan, I believe.
