I can't add any details to Rachel. Made my first visit to them in April. Very important buildings in the Revolution. They were owned by my ancestor 1751 to 1771.
Best place to check is the website, www.yorkhistorycenter.org, it's usually open April through November on Tuesdays through Saturdays with tours on the hour, but check the website for exact tour offerings, also your ticket is good for the History Center's other sites during the same day (ag industrial museum, historical society museum)
