The official site mentions a shuttle bus service, I also googled but the infos are not clear, so I hope to find some firsthand experience.
I have a flight with a stop in Fiumicino, I will arrive in Terminal 1 and the next departure is from Terminal 5, the transfer time is around 5 hours.
Is it correct that I should go to Terminal 3 first (using the internal transfer area) and after exit from Terminal 3 and take the shuttle to Terminal 5?
The terminal 5 has a waiting area with some shops or is just a terminal for departure? In your opinion is better to wait some hours inside Terminal 3 before going out to take the shuttle bus?
