Rome Airport - Campino

We are arriving at Campino airport with Ryanair at 11.55pm. We will not be able to get the connecting bus with Terressav. Did this happen to any of you? if so how did you get to Rome Central?
We asked our hotel to arrange a taxi but the cost is outrageous 45euro

This is what we did:
From the airport we got a Co.tra.l / Schiaffini bus line direct to Termini metro station.
To the airport - took the metro from Termini to Anagnina stop and then got a taxi to the airport (I think it was about 10 euro)

Eur 45 is good for taxi from Airport to Rome Central. I paid Eur 70 on a recent trip there!!! Taxi drivers in Rome are a complete rip-off...especially the ones waiting to pick up unsuspecting tourists at the airports!
