Hi - We have booked 2 places for the overnight ferry from Lipari to Napoli but as the website is almost entirely in Italian, and my Italian is weak I wanted to check: Is "A2Doppia Est DO/WC" an exterior cabin with a WC? I didnt' really understand. Is is too late to correct if we've erred? Can't wait to visit Lipari and to return again to Napoli!!
