Do you have wheel chairs available?
We were just there last week. It is $15 per person and they offer discounted tickets for kids and seniors.
I believe that it's $15 for an adult ticket.
Sorry I do not know the answer. We visited it and saw tickets a bit expensive. I think we saw 45 and 15 but not really sure. However, we decided to walk around the town near the museum which was really great. The town is really beautiful. Also, we went on Sunday with parking is free in all of the town property.
