The local guide at Pompeii was great. 3 stars because no free time in Pompeii. I should have read the description more closely - I didn't notice that Vesuvius is closed in the winter. Went to a mediocre museum in Naples instead of spending more time in Pompeii - not a good use of a couple hours.
Great guide, great views. A fantastic way to get a feel for the West side of Sicily in a day.
