You can easily go around in Seoul without knowing Korean. In most touristic places you will find Koreans who can help you in English. However, beware also that in most stores, many Korean do not speak or understand English. They are all very friendly however. Take Google Translate with you and you’ll be fine.
For consideration, Google Translator Korean sucks. If you just have to someone to say, I'd rather recommend you use English. However, the pronunciation should be as similar as possible in North America or England.
I think If they still have a lot of sentences to correct it, just sucks. The homonym translation is the worst of all. Non-Korean speaking countries don't really recognize what's awkward with it. In some cases, postposition translate is so bad that it is better to type it directly.
I found that Papago sometimes does a better job at translating English to Korean, but it’s true that it remains an automated translation and is far from being perfect. To travel and get to understand menus and other signs, I found it useful when I went to Korea.
Google may be useful for simple words or expressions, but it's too messy to write letters or write a long sentence. Maybe It's fine to use just to interpret signs and menus. They have already put Korean options in the translation for a long time, but the translation engine seems to have not changed much then or now. In other words, they don't seem to be interested in Korean translation.
Some users found this method to translates Korean on Google. It's not perfect, so just note it. First, translate English sentences into Japanese. And then translate Japanese into Korean. It's little complicate and sounds funny, but it actually works. It better than clear translating English directly into Korean.
They said in an article that improved the translator using the same neural network learning Korean, Japanese and Turkish. But I don't know why Korean translation is so crap like that.
