Coming back to Korea, it's always surprising to me how many things there are to do... You could spend a lifetime here and never see it all. Seeing it now with two young kids, our itineraries are different, but we still have a ton of fun! My in-laws live outside of Seoul, so we mostly see a different side of Korea.  If you're on a repeat trip, or a fan of slow travel, I would encourage you to visit a smaller town and ask a local for their recommendations (especially for food as there are sooo many good places everywhere 👏🏼)
