Our European vacation ends in Rome and to get back home, we fly out of the airport there (Rome Airport Fiumicino - FCO). Our flight leaves really early in the morning - at 7:30 AM on a Sunday. This airport is off to the west of Rome and not that far from the Ostia Antiqua site. Our plan was to take the train from Rome to Ostia Antiqua Saturday morning, visit the Ostia Antiqua site and then stay somewhere near the airport. Any suggestions as to how to make this work? I'm not sure where we can leave our luggage while we visit the site, and where the best (hopefully inexpensive) place is to stay that can be accessed via public transportation and from which we can get to the airport in the early morning hours. Any suggestions?
Also how early should we get to the airport for a 7:30 AM flight. I know here in the U.S., it is recommended that people arrive at the airport 3 hours before the flight--but I'm not sure if that applies in this case. But if we have to be there at 4:30 AM in the morning, I guess we will do that.
And for the morning, is Uber an option? Or should we go with a taxi. (I'm going to assume that public transport that early in the morning might not be an option.)
Thanks for any suggestions!!!
