We're kind of in the same boat but we have already seen the main sights of Seoul on previous visits. I've already been to Panmunjon, husband isn't interested. We've also done a free temple tour on a previous transit.
We are arriving on TG around 7am, departing on AC around 4:30pm in J class so have *A lounge access. I haven't found anything else of interest unless someone here has some ideas? I wish ICN had the free massages in the lounge like BKK does! Should we go to the Asiana lounge or is there a better one for *A?
