Hi union,
It seems that Orvieto (Umbria) has caught on to become a go-to, happening place. About one hour from Rome - a train ride to Orvieto, then a gondola up the hill, and a city shuttle bus to the main piazza.
It looks like there may be a Folk Festival in August. I couldn't find current dates; so not sure if they would coincide with your visit. Also, it will be packed if there is one. It appears, there is definitely something for everyone.
Browse the links I listed and see if you want to customize your visit or plan a little here and there and see what happens.
