Hilton HHonors - Hiltons in Korea Outside Seoul?

My son is going to school in Korea and I was considering doing some travel with my son outside of Seoul during a break in his courses. Does anyone have experience staying at the Namhae property? It is a Cat 6, but I got no hits on a search for the property, so it makes me wonder.

Any experiences at the Namhae property? Or the Gyeongju property either for that matter...??

Well.. researching this again and thought I would check if there were any HH posters that had experience at the 2 HH hotels in Korea outside Seoul

Planning a trip to Korea and curious about experience of the two properties outside Seoul.....just bumping this thread up in the hope of a reply or two :)
