Great place, we took the afternoon public tour. Our guide was very knowledgeable, but he talked way too long in the front area (over 45 minutes). Those in the group with small children or mobility or back issues couldn t stand that long so many lost interest or went elsewhere to sit and wait. Last year we went on the evening tour and would recommend that over the afternoon as the center is closed and you don t have visitors trying to get around you during the tour.
