Planning an October trip to Italy. On a previous trip, we stopped in Orvieto. I consider it a great stop between Tuscany and Rome; it has a lot to offer in a small town. The one improvement I'd like to make on my previous visit is a better underground tour. We booked one through the TI. It was okay, but I read later reports of tours that sounded much better than ours.
Can you recommend an underground tour choice, what it includes and maybe a link?
Thanks,
Brad
