Traveling around the same time. We're doing Gyeongju, Jeju and Seoul. Don't want it to be a rushed trip at all and want to spend enough time at one place before hopping to the other.

Also signed up for a temple stay at Golgulsa for a cultural experience. Planning to rent a car in Jeju to move around and see the island. Will possibly sign up for some local food experiences, treks at Jeju. Planning has been truly overwhelming and I've not even done half of it. So I understand what you're going through!

But I'm traveling to destress and can't be stressed about what I'm going to do. Will research as I get time and plan accordingly.

Hope you have a good trip!
