It is my understanding that guides are licensed in Italy for specific sites and that a guide licensed to guide at Pompeii, for example, may not be qualified or licensed to guide at other historic sites. I have also heard that a driver, even though he may be licensed as a guide, cannot do both things at once. Is this accurate?
I am planning a day trip from Naples to Pompeii, Herculaneum and will visit for a 1-2h period at a Museum in Naples that same day. We had originally planned Museo Nazional Archaeological but it is closed on the day we are in Naples. So, I'm now planning on the Museo Nazional di Capodemonte. I have a guide and believe for Capodemonte in particular a guide is very helpful. Should I be concerned that the guide who is taking us through Capodemonte is the same guide taking us to Pompeii/Herculaneum?
