You don't need an appointment. But I would check to see what time they open and close so you give yourself enough time to wander through the exhibits. You could easily spend 3+ hours there.
You can just show up during open hours.
You don't need to make any appointment. Just show up and you would be welcomed warmly with smiles.
You can just show up. You never need an appointment.
Just show up there. Make sure of their open hours. Also, there are several missionaries in there to help you with everything and tell you the history of each site yiu go through!
All visitors always welcome during open hours.
Anytime they are open you are free to go
