Worth spending the evening soaking in the hot pools. If you think of choosing between the adult pools and the deluxe spa, take the deluxe spa package. They also have a combo pack that will give you access to both (areas 1+3), but they’re kind of the same thing, so it’s not worth it. The deluxe spa is smaller, more private, has heated recliners and the pools look more picturesque. The adult pools were rather crowded. Although the deluxe spa does allow children, it was still better.
Amazing tour of Pompeii site. Went to National Archaeological Museum of Naples to view the artifacts from Pompeii... Definitely worth it to also go there to fully appreciate the historical significance of the area.
