Hi. Overall it's safe. Korean ppl don't understand english. So make sure u pick up simple lines like number, toilet etc... as long as u prepare in advance and know how to get to the places u wanna go, it should be alright.
There are friendly ppl u may meet and help u when u need assistance. No worries and just enjoy!
Hi, I saw that you went to Korea by own planned. Can you share your experience to me? I'm going this coming October and self planned too. Any things that I need to pay noticed? I'm very worry when I reach there I couldn't communicate with their people ><
