I'm booked on the Holland America Noordam leaving Rome on 20th July. We are flying to Rome with Ryanair, and will be arriving at Ciampino airport on that morning. I have been trying to find a shuttle company that will give me a quote for the journey from the airport to the docks, which is about 50 miles I believe, but so far have had no success. It is mildly complicated because after the cruise we are staying in Rome for 4 days, so the return journey is from the city itself.

Can anyone recommend a reliable and reasonably priced shuttle company?

try www.airportconnection.it. They have reasonably priced shuttle from airport to hotel or airport to dock. Hope this helps.
