DS who is 18 wants to go to South Korea for a fortnight in the summer, travelling independently and staying at an AirBNB. Obviously, now that he is 18, I can't stop him going (he has his own savings so can fund the trip) but the whole thing is making me nervous, largely because I know hardly anything about South Korea. If there is a genuine reason why it's a bad idea (as opposed to just fear of the unknown) I think DS will listen to my advice. As a family, we have traveled to quite a few places in Europe, but never further afield. Does anyone who knows South Korea have any views on how safe/risky it is for an 18-year-old from the UK to go traveling independently?
The reason for the choice of South Korea is that DS wants to meet up with a friend who he made on a school trip with participants from all over the world. Friend lives in the US, but his family are from Korea so he is going to Korea to see relatives. Obviously, if Korean speaking friend who knows the country is there to show DS around, it will make life much easier, but I am conscious DS doesn't know friend that well, so I would like to be confident that it would still be OK if for some reason the friend didn't show up. DS also has another friend (in the UK) who was on the same school trip and is also travelling to Korea at the same time, so DS would not be totally alone if US friend didn't show up, but UK friend is not a really close friend.
Advice welcome!
