We used all three facilities this time, which felt quite worthwhile. However, to use Okayama Castle and Korakuen Park, you need to exchange tickets at the museum next to Korakuen Park before you can enter. But the museum opens late, which is a bit inconvenient. It would be more convenient if you could exchange tickets at Okayama Castle as well.
