I finally traveled out of Incheon Songdo and visited Seoul and Busan. I had no choice since my son was visiting from Utah with his girlfriend. Even with the limited time, we were able to visit some of most famed sites.
Gyeongbokgung Palace: Foreigners get a fairly good discount; the ticketing staff only asks how many tickets are needed; when I read the entry fee listing, it had big discount for the foreigners. So, you must mention that you are foreigner.
Changing of guards ceremony: At the time of purchasing entry tickets, make sure you ask what time the ceremony is; when we visited, it was at 2pm daily.
You can rent the Korean traditional costume (Hanbok) by the hour and stroll the palace (this activity is very popular and well-liked by the tourists); these two couples are from Hong Kong and Phillipines, having a honeymoon vacation. I sat in shade and enjoyed watching men, women and childeren of all ages wear the Hanbok, with hair/head accessories matching their costumes.
National Palace Museum of Korea: There are three floors of amazing and beautiful history of S. Korea.
I finally got to visit the statue of my favorite historical figure, Admiral Yi Sun-Sin (a famed Korean naval commander in the Joseon Dynasty). It’s located in middle of very wide median, in front of Gyeongbokgung Palace
