I've seen other questions like this, but I don't recall an answer.
The thing is, our hotel is close to the Ara Pacis and Castel Sant'Angelo, but we want our "free" sites to be the National Museum of Rome and the Colosseum/Palatine Hill. To do this, we would catch the Spagna Metro and go down to Termini and then Colosseo. Then we would need to backtrack to do the other two at a discounted rate.
Is it possible for us to walk over to the Ara Pacis, show them our Roma Passes, and get the discounted rate instead of using one of our free entries on it? Thanks.
