We will be traveling to Florence and could spend a few days in Bologna or even in Parma. We would love to tour cheese and balsamic factories, and maybe even some vineyards. We have found many tours on line, all receiving rave reviews on TA. The tours are fairly expensive for a family of 4 so we are investigating whether we could visit these places on our own if we rent a car.
Does anyone know if this is possible to do?
If not, do you have a recommendation for which tour guide to use?
