We are travelling from Ravenna to Lucca by train around Sept 4th. The basic journey, Ravenna/Bologna/Florence/Lucca is fairly complicated but looking at the map and timetable we could complicate it further by going via Poretta Terme and Pistoia from Bologna to Lucca. Is it worth the diversion and should we plan to stay a night along this alternative route? We do have the time. Mature couple sightseeing.
