I have an Euro account, can I play this account from Korena?

Plan to travel to the far east, but still like to play from overseas.

If your asking whether you will have to change server; No, you can keep playing on euro server

no, i am not asking that.

Yes you can play it. It's the same client. If you can't use a korean client, just install the one from the official page.

Or of course the CDs you got with your game.

Why would it change if played in Korea than in Europe beats me. Not like the internet you play on will change drammatically, to force you to be Korea server than Europe.

It should not have any affect.

I play from two different countries, just gotta have the cleint installed, type in ur email and pass and ur good to go =]

you can play your (unbanned) account from anywhere in the world that has a connection to the internet and the guildwars client installed.

You can also switch your account to different servers a limited number of times (check the account management before you get on a specific character)

But it should work just fine, since I've seen Koreans on US anyway.
