Bologna is the closest airport to fly into. Last year, we chose to travel straight down and stay at a hotel in Ravenna - there are few taxis available to take you from
Ravenna to the actual port, which is still quite a distance away. If you chose this option, make sure you book a taxi at the hotel as soon as you arrive. We chose to stay in Bologna overnight on leaving the ship (Sunday) and fly out the next day. The plan was to have a nice meal in the evening to celebrate a friend’s birthday - there were plenty of restaurants in the vicinity of the hotel but none were open - apparently, they don’t open Sunday evenings!!!
