Country house is really great!! Food is good, staff is friendly, prices are reasonable.
If you want to go to rome, i suggest doing it on your own and taking the train. You can park your car at CAPO base, take the Ali bus to the train station (Ali bus costs 3 euro and runs every 30 minutes!). Take the train to rome and use the Metro to get around. We have gone several times and spend very little money, much less than the actual tours, and we always have a good time. And this with small kids so it can be done! They seem to speak more english in rome, especially at the tourist sites and many hotels. We have been to some wonderful resturaunts in rome as well, and they spoke english and had wonderful food.
Also, using the Ali bus, you can travel downtown and see all the nice things naples has to offer. The archeological museam is REALLY easy to find if you take the metro.Once again, park at Capo base and take the ali bus to the train station, ali bus only makes 3 stops, the capo airport, train station, San carlo theater, so very easy to use and it makes this loop, every 30 minutes till 11:30pm. Using this system, you can see all the castles, zoo, parks, museams, churches, etc. Ive been downtown lots of times and never had a problem.
You can also take the train to Pompeii, Herculaneum, Sorrento, Ercolano, and other cities around as well as take the bigger trains to the bigger cities.
Also, you should really try to drive around more. I used to get lost so many times, but it forced me to learn the area and now i pretty much know this whole area, just from being lost and having to find my way back, many times without a GPS (cause i am forgetfull!).
I think the farther north you go, the more english they seem to speak, and the easier it is to get around and do things. I am a big fan of public transportation, we have never had any issues with pickpockets or anything. So dont let it scare you. As long as you are watchfull, you should be fine!
