Hello,
I'm going to visit Seoul in October and I have a few questions about the palaces (Gyeongbokgung, Changdeokgung, Changgyeonggung and Deoksugung)
First, I woyld like to know if they are going to be open on September 30, during the last day of Chuseok.
Second, some of the websites to the palaces are not working, I read about a Moonlight Tour, meaning a night tour through Changdeokgung, how can I book? The website doesn't work.
Can I buy onsite the ticket for the Secret Garden of Changdeokgung for another day? Or it's only available for the day of the purchased ticket?

Thank you
