We are a family of 4 (with children aged 18 and 14) who are travelling to Italy between 3-11 August. Over the course of the stay we are plannknb to get the train from Milan Malpensa (via Milan Centrale) to Rome, then Florence, then Venice, then Peschiara del garda, then Milan Malpensa airport via Milan Centrale. Is it better value to buy a rail pass to cover all the trips or book individual train trips? Which site is best to use to make the bookings as well? Thanks.
