I read the post "to and from FCO airport" and it was very helpful. But it seems like most of the options will not be available when I land. My flight is scheduled to get in at 11:15pm. But the time I get through customs and claim my baggage I'm sure it will be after midnight - maybe even 1? I don't know how long customs will take. I assume that taxis will be available that late, but I was hoping to find a cheaper option. Any suggestions? Thank you!
