Subject: Reservations Uffizi - web site?

Hi Ziners, A few months ago someone posted a web site where you can make reservations for the Uffizi. I did a search and I can't find it. Does anyone have this web site? I've been trying to make the reservations on phone & it so far it is either busy or they put me on hold forever. Thanks for your help. Headed for Italy April 30th. Can't wait! Maria Redondo Beach, CA
