First time in Italy. Our thought is to leave Sorrento on the train some AM, visit some combination of Pompeii, Herculaneum, and peak of Vesuvius and end up in Naples in the PM, next day see the archeoligical museum and maybe 1-2 other sights in Naples, then move along with our vacation to Rome.
We have a bunch of questions:
1) Is this doable (reasonably), or should we eliminate 1 stop?
2) How much time is required to make each place a worthwhile stop?
3) Should we forego Pompeii, as many of the artifacts are in Naples museum, for Herculanem only, and do Vesuvius peak?
4) Is there storage for baggage at these places?
5) Is it worthwhile to hire a guide?
6) What's the best way to get as far up Vesuvius before finishing the hike to the peak?
Thank you in advance for your thoughts and response.
