we are planning to stop by pisa on the way from florence to cinqueterre. we only want to visit the leaning tower--either hire a driver or just get a cab from the train station. run there run back, catch a train out. we don't want to stay there, eat there, nothing. just leaning tower on the fly.
how much time do we need? in other words, how many hours later should i book the train leaving pisa? and can you give me your estimation with and without actually climbing the tower.
