Excellent company and docent- solid five stars. The film at the free tour explored how the factory evolved throughout history. I liked learning about it a lot. The kids enjoyed free ice cream afterwards. Minus 2 stars for the very rude receptionist in the front desk. She is an African American lady who gave us eye rolling looks for asking for water or ask to use the bathroom while waiting for the tour to start. I have never met a receptionist who is as rude as her. With this kind of attitude, she should be fired. It is sad that her behavior tarnished my experience at the tour.
