We're planning our first trip to Italy, flying in to Rome and spending our first 5 days in Siena.
Is it possible to take a regional train from the airport to Tiburtina and then catch a Baltour bus from there to Siena? The Rome2Rio site indicates that buses run from FCO to Tiburtina (but only every 4 hours) and then on to Siena but the Baltour site does not show a Tiburtina stop. In short, I need to find the best way to reach Siena via shuttle or a combination of train and bus. Suggestions?
