My family along with another family will be going to Italy this summer. Kids range in ages 6-12. We are staying in a castle called Villa Emilia which is 80 miles from Rome and 45 miles from Naples. Can anyone recommend day tours for us to go on? Or have any recommendations for us in general? Our kids are well behaved and we will also have access to a babysitter.
Thanks in advance for any and all advice/recommendations!

It's not at all clear where you're staying. There are tons of villas for rent, and Villa Emilia is a very popular name. The only one I see that sort of fits your description of the location is in the town of Rocca d'Evandro. There is a castle (rocca) in that town, but the villa is a different place from the castle. The castle is owned by the town, and has been under restoration since 1983, supervised by the government agency that supervises cultural heritage! (That's the way things operate in the province of Caserta. I'm sure it's put vbread on the table of three generations of government employees.) The castle is not open for visits at all.

In fact, I'm a little concerned about your rental. I don't see that property on any list of villa rentals in the area, and can't find any reviews, either. In fact, I can't even find it in the Italian White Pages. Did you rent it through a reliable agency?

In the area, the two places I know that are well worth a visit are:

The Regia of Caserta, the royal palace of the Bourbon Reign

I accidentally hit "Submit" while trying to correct a typo. It's "Reggia". Let's start over with that.

In the area, the two places I know that are well worth a visit are:

The Reggia of Caserta, the royal palace of the Bourbon Reign of Naples. It's one of the world's largest palaces, and has a magnificent English garden.

The Abbey of Montecassino, on the site where St. Benedict founded his first monastery over 1500 years ago. The large and splendid abbey was destroyed by Allied bombers in World War II, under the mistaken impression that German forces were using it as a base for shelling the troops advancing towards Rome. The abbey has been completely restructured.

The location is also not far from the seaside towns of Gaeta and Sperlonga, both of which are very popular in the summer.

Further away, about an hour and a half by car, is one of Italy's prettiest towns, Sermoneta, with a beautiful castle you can actually visit.
