Dear, Marc,
I've spoke with your guide to understand what's happenned and he got surprise since he said that answered at all your questions and that you've been the most interactive clients for the Galileo Museum which is one of the most exclusive in Florence.
Please, send us an email to tours@keysofflorence.com, I'll be happy to offer you an other tour with another guide in order to solve all the unanswered questions about the museum.
Regards,
