Use Naples itself as the low-friction option
The historic center begins close enough to the port that a city day can preserve the most flexibility for food, museums and neighborhoods.
NAPLES · CRUISE PORT
Naples cruise port: city, Pompeii, Amalfi—or a day that actually fits.
Naples is unusual because the city begins almost at the ship, while Pompeii, Procida and the Amalfi Coast create very different time-and-risk decisions.
Treat Pompeii and the Amalfi Coast as different decisions
Pompeii is a transport-and-ticket problem; Amalfi is a longer regional movement problem. They should not be presented as interchangeable day trips.
