I went to the main office in duomo , waited 30 mins to talk to gentleman. Advised me I could get tickets cheaper by going to opera house at 5pm. Waited there for almost two hours. Tickets were in second row and had no view. Lots of empty seats with no view.
What a waste of time. Terrible booking system, I'd avoid.
