We are currently planning a week in Rome (some of that will be visiting with family), possibly 2 nights in Florence and 3 nights in Venice. This will be Sept 18-30 and our children are 11 and 13. I am trying to prioritize sites and museums to no overwhelm the kids but also to try to be somewhat cost conscious too. We spent a year in Ireland in 2008-2009 so the kids were exposed to many museums, galleries, ruins all over Europe but we didn't visit Italy that year. So what would be the must do places and what could be left because we are seeing something similar but better in one of the other city. For example is we go the the Academia and Uffizi in Florence, would you skip a place in Rome of Venice.
Also - does anyone have any idea how far in advance the calendar or events for Pope Francis will come out. The timing works out that we may need to go to the Papal Audience Wednesday morning and take the train to Florence in the afternoon. What is the earliest we should book a train. Pope Benedict often had the audience at a different location in August/September. Would this be the case with Pope Francis - as that would definitely complicate things? However if there is a Mass the previous Sunday, that could be a better option.
