Well, the flights are now booked.
Leeds Bradford > Paris CDG and
Venice > Leeds Bradford.
In between is still to be decided, but could be something like…
Paris > Lyon > Marseille > The Cote D’Azur (Monaco, Nice etc) > Genoa > Florence > Rome > Naples > (Sicilly >) Venice .
Next steps really are to decide on a few details like hotels in Paris and Venice. I think the middle bit can take care of itself. Feel free to suggest things to do though, and lend me books and that. Please!
