We will arrive at the Pisa Centrale station and will walk to the Field of Miracles to see the sights. We then will take the bus on to Lucca, which leaves from near the Baptistry. To prevent backtracking I would like to stow our bags somewhere around the Field of Miracles, like the San Rossore station or somewhere else. I understand there is a bag check at the Tower, but it is only for day-pack sized bags and we will have carry-on sized bags. Any ideas are greatly appreciated!
