FCO Airport question

Hard to say
Flights can be delayed
Passport control can be crowded at that hour

Most driver services will monitor your flight so they will know what time to expect you

Thanks Christine for your reply. I edited my post. Our driver will monitor our flight to pick us up.
However, I'm working to schedule a lunch stop in Orvieto on our way to Florence, so would like to have an idea for scheduling our day so we can make a lunch reservation at a desired restaurant. Thank you.

You could phone the restaurant as soon as the driver collects you, or as soon as the restaurant opens, and book your table. The driver will be able to give you an approximate time of arrival.

Do you have a certain restaurant picked out?
Because if not, and if you are not planning to sightsee in Orvieto, there are many rural restaurants on that route that would be much easier to access, rather than having to drive into Orvieto.

If you arrive FCO at 7:30, you should be out of the airport by 8:30 or even earlier.

The drive to Orvieto takes about two hours. So you will arrive far too early for lunch...even if you leave the airport at 9:30.

You might want to choose a restaurant in Tuscany, much closer to Florence, for your lunch, if there is no specific reason to enter Orvieto. There are plenty to choose from, not far off the A1. Just make sure they are open on Sundays.

Too many variables for anyone to give you an exact time if you need to make a reservation.

Planning to hire a private driver, who will monitor our flight

Have you looked into the cost ? One source I checked has an almost 700 euro fee to go FCO to Florence. Adding in the waiting time in Orvieto, I suspect the trip will cost close to $1000.( and more wouldn't be a surprise)

If you have a specific restaurant you want for lunch, I would contact them now, explain the situation and see if they would be willing to accept a reservation once you are in the car and on the way.

Is it Easter Sunday or some other Sunday?

Travel times:

FCO to Florence via Roma Termini by train: 2:30 and up

FCO to Florence by car: approx. 3:00 (per ViaMichelin)
FCO to Orvieto to Florence by car: approx. 4:30 (per ViaMichelin)

I really, really like Orvieto, but to me it's a place to spend at least a full day, not a place to have lunch on my arrival day in Europe when my body clock will be so messed up I may not even be hungry at midday. Not to mention the cost.

It sounds like your plan is to Fly coach ATL-Rome, have a driver drive you to Orvieto for lunch, wait for you and then drive to Florence. Is that the case?

Thanks everyone for the replies. I have the insight I need now.

We will be spending 3-4 hours exploring Orvieto, with lunch towards the end.

All the best!
