Why don't you try over on your roll call for this cruise on cruise critic - you will get a better chance there.

You never know - someone may sign up who is interested.
Terravision Express Shuttle
A dedicated coach service for Ryanair, Air Berlin, and other some Airline passengers operates between Ciampino airport and the centre of Rome (Termini station).
Tickets cost Eur 8 one-way and Eur 12.50 return. From Roma Termini down to Civitavecchia the train is €9. This may be a whole lot cheaper than getting a taxi. Try contacting www.romelimousines.com for a private transfer quote...hope this helps.
Wow - what an active roll call - hope you have a good Meet and Mingle .
