If you are staying in the hotel, you should be able to come at any time. When I came up, I knew that I could make an appointment to explain it, but it was a little small. It feels like if you come here specifically for this museum, even if it is free, it is a bit unworthy. The main thing to explain is that some of the history of this Peace Hotel has something to do. No wonder the Dragon and Feng Hall is so expensive, it is a state banquet level.
