Any recommendations for things to see and do whilst staying in Parma in July? We will be visiting friends for a long weekend, but need to occupy ourselves while they are at work. Is it possible (and worth) visiting neighbouring cities such as Verona, Modena, Genoa etc, or is the travelling too much? Can you do it by train/bus, or do you need a car? Grateful for any tips to make the most of our trip, as we don't have funds to repeat it in the near future! Thanks.
