Has anyone done a full Rome city tour using the Hop On Hop Off bus service? I’m debating if it’s a better option than walking or joining a group tour. I found this great Hop On Hop Off Rome itinerary blog that explains each stop, what’s nearby, and even time estimates. It’s very helpful for building a one- or two-day Rome itinerary. I'd love to know how it worked for others—was it efficient, on time, and worth the ticket price?
