You'll be able to get by just fine without any Korean. Even when I try to speak to people in Korean, they come back at me with English (the same happens in Japan, too, though, but not as often as it does here). There's English everywhere, especially at the touristy places. But if you wanted to, you could learn to read and write Korean in about 10 minutes. Pronunciation is a little difficult at times, but if you can read things, you can get around way better, particularly because you'll be able to read the bus routes on the sides of buses. Busses here are super convenient, they run everywhere and run pretty regularly, and they're air-conditioned!
I'd say have an adapter for plugs (although you're in Europe so I don't think it'll matter for you). When they say something is spicy, it's probably very spicy and you should take their word for it. Summers are so hot and humid I find it hard to live. Things are way cheaper compared to Japan, though, so you won't need as much money. I have no idea about hotels and stuff, so I can't help you there. It all depends on what you wanna do. But if you have any general ideas for things, let me know ♥ Flights to/from Japan are pretty cheap, too.
