I previously posted about Monday issues for Rome and we took the suggestions to heart and my family is going to go to the Colosseum that day. Hooray.
Now...last time we were in Rome, you couldn't go underground. My brother-in-law (who has never been to Rome) wants to go both up and down with some guided tour.
Suggestions please for an excellent guide/tour. Much appreciated and we'll get it booked asap.
