Try to find the roll call for the cruise and post there instead.
As an alternative, have you looked into Tuscany bus? I haven't researched Livorno/Florence much, but I did a nice "tour" with them to Lucca and Pisa at a very reasonable price. It's more or less just the transport if you want it to be, but you can also pay a little extra and get more of a tour. They did Florence as well when I was there in December 2023.
