My wife and I recently returned home from a fabulous trip to Italy (Cinque Terre, Sorrento and Naples). We are huge Rick Steves fans and have used his travel guides extensively on each of our last four trips to Europe. The information and "travel tips" he provides are unbelievably helpful and have greatly enhanced our vacations. The whole trip was excellent but the definite highlight was our tour of Pompeii. I am a huge history buff and the ancient site really blew me away. I would HIGHLY recommend to anyone planning to visit to hire a private guide. We used Gaetano Manfredi which was recommended by Rick in his book covering the Naples/Amalfi Coast area. Gaetano was extremely knowledgeable and really made Pompeii come alive. On top of his expertise, he was very entertaining, professional and is a very genuine and kind person.
Keep On Traveling!
