Hi..I am planning to visit Italy in Mid-march for a total of 5 days with my husband and 3 year old son. Since its a very short visit, I would really appreciate help in planning for the trip. Is it possible to cover Milan, Florence, Rome and Pisa? What about Vatican city? We will not be going too deep into art. Please suggest the route that we should take, and the most economical way to get to these places.
