We're group of people (12 adults + 5 children) who're going from Milan to Genoa and I've found on Trenitalia homepage an info that : "Groups are reserved a special offer on all trains and destinations, and for short-medium and long-distance journeys. On our trains within Italy groups of at least 10 paying persons are entitled to reductions."
One little problem - I can't find where I can buy those tickets :)
Has anyone else tried to buy group tickets? Any suggestions?
