Excellent
Two guided tours in one day is maybe a bit much in one day, especially in the heat. We had to cut the Herculaneum tour shirt & seek shade to sit down. Not the guides fault, he was very good. We later found out that he did not include the Artifacts museum on site, during his tour. We made our own way there & enjoyed it, but the rest of our group missed out. It is a very good option as, besides being interesting, it is air conditioned. A welcome bit of respite on a blistering hot day.
