We'll be in Naples (well, Pompei & Sorrento) in a week and a half, and I very badly want to see the Cave of the Sibyl. Has anyone been recently? If so, how easy is it to get there by car, and is there parking to be found? My heartfelt apologies if I am just missing something- I've been searching tripadvisor for an answer and keep coming up empty-handed. Even a nudge (shove?) in the right direction would be much appreciated!
