Hi,

Quick question; how much time does it (roughly) take by car (taxi) from Rome city center (Auditorium Parco della Musica) to FCO at a Friday around 1530?

I will most likely run short on time, so I need to know how much I can cut it short.

Regards,

Not always predictable, you may be able to do it in 30-40 mins but I'd allow an hour to be (pretty) safe.

I agree - it can take as little as 1/2 hour, but at 1530 it could easily take an hour.

And, the walk from the main train terminal to the track is very long, compared to most stations I've used. The walk can take 10-15 minutes.
