Has anyone used the site http://www.polomuseale.firenze.it/english/benvenuto.asp
(referenced in the Italy updates by Rick Steve's)?
I just tried booking 2 tickets for each of the sites, when it came time to check out, I received an error message. When I went back to try & re-purchase them, these time slots were now gone (I assume I had previously reserved them). So my question is, will the slots be reposted and does it normally ask you for a credit card to purchase and do you get a reservation number.
Thanks
