We are staying Venice the night before the cruise. I’ve just tried to book transfers from Marco Polo to Ravenna but was advised that I could not get them from the airport as my flight arrives a day early. The operator stated that the transfers were tied into the flight details. My flight number and arrival time are the same on our arrival day and the ship departure day so does this mean we can get a transfer from the airport? If not we need to travel to the people mover and get the transfer which is £91 return each!
