We were lucky enough to visit Sorrento and the Amalfi Coast for two weeks at an all inclusive resort that we neglected to take advantage of due to the sheer amount of sights in the area. Capri and Positano were certainly highlights. Not cheap ones, but it was a honeymoon after all.
Trips to Pompeii and Herculaneum, hike up to the top of Vesuvius and day trips around the bay of Naples were always well rewarded by some of the finest food I have eaten. Mainly Pizza accompanied by some truly amazing wines.
