I need a bit of advice. Having been to Florence before, I would rather not spend a full day in Florence when our ship comes in to Livorno. Instead, I would like to take the train from the port to Lucca. Spend a few hours in Lucca and then take the train to Florence and go to the Uffizi Museum. then I'd like to take the train back to port. Is this doable? We are in port from 7-7.
