Gina's gone out with Stephenie to a drawing lesson. I'm just trying to answer you for her because she might come home late today.
Yes, it's true that the holders of Portuguese passort don't require visa to stay in South Korea. We went there last year and were allowed to stay for 90 days. I don't think anything has changed so far. If you really want to know, I will ask a friend of mine who works in a travel agency tomorrow (Monday) .
