We fly in on a Saturday evening. We will have a full day Sunday and a full day Monday for sightseeing. We are staying at the Artemide Hotel. Would like to go to Vatican City and also see the Colosseum and Forum along with smaller interests like the Spanish steps and Trevi fountain. I need help breaking this into the 2 days. Assuming Vatican City will have to wait until Monday and the others can be done on Saturday? Understand that we will need transportation to get to Vatican City and we will be walking everywhere else. Itinerary help please!!!
