I've just returned from a 15 days trip to Korea. Being able to read Hangul was helpful, especially when trying to read menus, but in most places, road and subway signs were bilingual (English & Korean). In many ways, the country seemed to be light years ahead of other places (I'm from Switzerland).
By the way, Korea is absolutely worth a visit. I think I'm infatuated with it right now. In the short time I got to know a couple of very wonderful people.
Did you know the meaning of the words that you translated from writings to "words"? I mean, I could read korean letters and words if I know the alphabet (somewhat) but I dont know what it means anyways.
There's a surprising amount that's in English, and survival words are relatively simple.
e.g. 화장실 - bathroom. You don't need to make a complicated sentence when asking where one is. Just 화장실? is enough and everybody knows you're a foreigner anyways and will know what you mean.
Hello, goodbye, thank you, your welcome, are similarly easy.
Food words are relatively simple and regular and if you drink alcohol there's relatively few to learn about.
I agree, Korea is sadly way underrated as a tourist destination. Amazingly fun, safe, tons to do (generally speaking). Everything from hiking to nightclubs. Ridiculously good public transport, fun stuff for tourists to do, interesting culture, amazing food.
I've been there quite a few times and have absolutely loved every minute there.
