For a Naples enquiry, tell us whether the collection is in the city or elsewhere in Campania and supply the exact address. A pickup from outside Naples changes the starting leg, so include the municipality and any practical meeting-point information instead of relying on a broad “southern Italy” description.
Because the route continues a long way north, useful planning details include the pet’s normal feeding and rest routine, any medication or mobility needs, and whether a suitable crate or carrier is part of the luggage. Give the complete UK destination and passenger count too. The journey can then be discussed as one trip with its real endpoints, not a generic estimate.
Rome and Florence offer central-Italy comparisons. The Marseille route is a separate South of France journey.
