Not sure what exactly you're jealous of, but if it's Pompeii, then all I can say is try to do it. It's an amazing place.
And get a good tour guide, as they will make your visit. Ours wasn't great, but still conveyed enough to have me absolutely staggered. The scale of the place was overwhelming enough (it's surprisingly massive), but immerse yourself in the facts (eg, it was buried under 10m - yes, metres - of ash and pumice) and it's simply staggering. It was a 'bucket list' thing for me, and actually surpassed expectations.
But Naples was a absolute dump. We only drove through it, and some parts might be nice, but if you're going to visit, I'd recommend staying further afield, like in Sorrento or along the Amalfi coast. Or, as we did, visit on a cruise.
