We are driving from Abruzzo a family of four. I would like to visit Val d'Orcia area, Siena, short visit to Pisa and another day for Florence. I don't think using the train would be best, since we have a car to use? I realize time is short and would like to minimize my driving. Two separate nights of two or just one base I'm considering, just don't what towns would be best. I would like to be in or near a town that may have some night life for a walk or shops . After Tuscany then we head north. Any assistance would be great. Thanks
