Hi, Me and my mom together with my two sisters are going on a tour and I found out that there is this combo ticket in which we can purchase so that we can go to 4 palaces and the Jongmyo Shrine. I would like to ask if I can buy the combo ticket at the Changdeokgung Palace for we are planning to go there first.

Also another question, will the combo ticket be available for a week with one visit per palace for we want to go to Gyeongbokgung and Jongmyo Shrine on Wednesday.
