My partner and I are looking for a Greek island pass (6-day). Unfortunately, we didn’t buy the pass before we started traveling and are now unable to receive one as the shipping time is 1 month. We are currently in Italy (Milano) and were hoping to buy one here but they all seem very confused at the station. Is there anywhere in Italy that we can buy such pass? Preferably around Milano or Rome.
Trenitalia should be able to sell it, including at Milano Centrale station.
In their Interrail FAQ, Trenitalia mention the complete series of Interrail passes here. Almost at the bottom, the Greek Islands passes are listed.
And then they say they sell Interrail passes at the Trenitalia ticket offices and authorised travel agents. They give a list of their sales points, here are the ticket offices in Lombardia (including Milano Centrale) and here in Lazio (including Roma Termini).
Maybe it helps if you show them some of their own information...
