Has anyone used the airport shuttle recommended in Rick's book, Rome Airport Shuttle? The price for two people is just a couple of euros more than the price of two Leonardo Express tickets, and they will take you straight to your hotel.
My concern, other than general reliability, is telling them what time to pick us up. Their website asks for a pickup time, but then says
No extra charge for waiting time up to 1h30? after landing time
The sign-up form asks for flight number. Is an hour and a half long enough to deplane and clear immigration? If the plane is late will the shuttle company be aware of that? We probably will not have cell phones, so calling to reschedule might be difficult. And it's pay in advance, so I'd want to be reasonably sure that we make the connection.
