Is the Colosseum underground area great and we shouldn't miss it? Or not a big deal?
We have a verbal agreement with one of the RS recommended guides to tour us through the Colosseum, Forum, Palatine, etc. But after agreeing to use her, I discovered she does not have formal tour guide status, so we need to purchase her ticket. Not a big deal. But then I learned about the underground, and we kind of want to do that. We learned you can only do that with a tour guide. So I mentioned it to her, and she said not to get that kind of ticket. Presumably since she can't take us there.
We're still a month out, so I don't think it would be putting her in a bind to cancel her and go another route. But is including the underground worth making that change? I'm not sure what to do.
