My family and I ( two pre-teen kids and a husband) are spending time in Naples. We had in mind to See Pompeii, Herculaneum and Mt Vesuvius in one day. The Caserta Palace another day. So my question is, what if possible, be the best way (and a reasonable price) to see the first three or should we perhaps put Caserta with one of them. I have a fair idea that they are in different directions and wasn't sure how good public transport is.
