11/6 night - Move to airport hotel or remain at IC?
(try to get a high floor room as teh hotel is squizzed just above the piazza di spagna)
11/7 8am - Depart FCO
i ve been many times to Rome and gonig to the airport to catch a flight at 8 am should not be a problem
60 min taxi drive at 5.30 or so should be ok ( unless there is some construction work, the IC concirge should it know in principle)
i would recommend a drink/dinner in the radisson on the last floor (swimming and a restaurant open air) - make a reservation - panoramic view

- great stuff
