Jim and Hank, I want to thank both of you for the incredibly useful information you give. in fact, i was thinking about taking the latest possible train back to civitavechhia
now, my new questions: is there a subway near colosseum to get to the termini station as we are planning to start with vatican and end with colloseum? also, i'll greatly appreciate if you'll tell if we'll be able to cover the following in one day (by walking): vatican (with stop at st.peter basilica only, no time for vatican); piazza novana, pantheon, trevi fountain, spanish steps, palatino hill, forum and colloseum? is the correct order? also, i'm using google directions for how to get from one place to another. do you know if they are reliable? thanks a lot!
