I want to take a train from Florence to Pisa... and then afterwards (an hour or two later) continue from Pisa to Lucca. Can I/should I buy one ticket from Florence to Lucca and after my short visit in Pisa, just validate it (again) when getting the train from Pisa to Lucca? Or do I need to buy two separate tickets?
If I do indeed need to buy a 2nd ticket.....
On Google maps street view, I don't see any ticket machines at the Pisa San Rossore station (which is where I'd like to get the train for the Pisa to Lucca leg)... so I'm trying to figure out where I can get that ticket (without using an app).
