Rome was spectacular.
If you are on a cruise, one day ( hours) to see Rome is not enough to see all. You get a glimpse of Rome. I recommend to take the hop on hop off sightseeing bus.
Beware of traffic in Rome, it takes time to go back to Roma Termini (train station).
Rome is definitely one of the places I want to return. I didn’t have time to go to Vatican city TT, next time^^.
