It’s totally doable by train, and worth it to stop in the city center and walk everywhere! I’ll put in a plug for St. Peter’s and Piazza Navona as well as Trevi Fountain. All within walking distance (and assuming he has no baggage to lug around with him!).

Enjoy!

Thanks for the plugs! I am going to check them out. I definitely want to see the fountain! We shouldn’t have too much luggage. I imagine that it will stay at the airport and be put onto our connecting flight to Cairo. We will only have our carry-ons. Since we are leaving the kids, that means just my purse (maybe) and my camera. Thanks so much for responding!

We did get to go to Rome. Thanks for your advice. We didn’t get to see much, but we did get to see Trevi Fountain. I loved it! It was gorgeous. Thanks again!
