I am heading to Rome in April. It is my third trip there so my wife and I are trying some new things. One of the things I want to see is the underground and ring tour of the colosseum. Most tours were very expensive $100+ but the coopculture http://www.coopculture.it/en/events.cfm?id=6#) tours seem incredibly reasonable at 9 Euro plus entrance. I am just wondering if you can use the Colosseum entrance from the Roma pass with this tour? Thanks in advance.
Also has anyone taken this tour? Is there anything I should know before I do it?
