Transfer from Rome (FCO) to Civitavecchia

[Jools2]

We are flying into FCO arriving 19:15 on Friday 9 May and staying 2 nights in Civitavecchia before the catching the cruise on Sunday.  I’ve been looking at transfer options, the options appear to be the train, taxi or private transfer. Train will get us in quite late and will then involve a taxi to our accommodation. Last time we were in Rome we caught a bus from the airport straight into Rome and it was perfect for or needs but can’t see a bus that goes to Civitavecchia. 

Long shot I know but is anyone else arriving on afternoon/evening of 9th and would like to share a transfer? Or has anyone done this before and can recommend a good option. 

Many thanks
