I think if you're more comfortable with a Tour, then that's the way to go. We prefer to go at it alone -I enjoy the research and planning part. As far as driving goes -it REALLY is not that bad. In fact, we had a blast -stopping where we wanted when we wanted. Ok..so we did end up in a few people's backyards unexpectedly, but they were all very welcoming and amused at the tourists who spoke broken Italian. I would never recommend driving "in" Rome or Florence(or any other large city) -it's simply not necessary. We did drive out of Rome and in to Florence with no problem.
