I use them every time I fly into or out of Rome.

We've used Rome Cabs (a car service despite the name) a number of times. Always very good service. Send them an email stating your needs and you should get an answer within 24 hours.

One time Rome Cabs was fully booked but they found us another car company which worked well. Nice company.

Used Rome Cabs last week and the were fabulous. Our flight was 2 hours late and the were still right there waiting for us when we landed. We were in a 6-seater sprinter van because we had extra luggage (wine suitcases!) but I’m not sure If they have anything larger. Probably not because it’s so hard to drive in some of the very narrow streets in Rome.

Another endorsement for Rome Cabs.

We picked up our checked bags followed the taxi signs got a taxi for 50 euros cash to our hotel near the central train station area 4 hours ago. It was easy

Taxi is easy from FCO but OP has 11 people and luggage so they’d need at least 3 cabs or wait for 2 taxi vans

Car service makes more sense

If you're staying at a hotel, contact them and see if they can book it for you. While I only departed from Rome last week, we booked a car service through our hotel near St Peter's and it was 80€ for 4 people in a large van to get to the airport.

Thank you everyone! I have emails in to both Romecabs and the shuttle limousine service. I think the older grandkids (18,15,and11) would be fine using the trains, but the 1 and 3 year olds might be difficult to manage with luggage.
