We will be going to Italy next year on an RS tour that doesn't include the Colosseum. We'd like to arrange a Colosseum tour, preferably one that includes the underground, on our own. Any recommendations?

You cannot do the underground on your own. You can only access it with a guided tour or with Coopculture staff accompaniment.
Editing: Oops, pretty sure I misread the question. You probably meant that you want references for a guided tour, not that you want to visit the thing on your own? If so, then Laurel and Henry have you covered! :O)
I highly recommend Sonia Tavoletta. She has guided us and our friends and many on this Forum.
