We are planning an early September trip (2 nights in Naples, 3 nights most likely in Positano, and thinking 3 nights in Ravello). Our flight out of Naples airport is at 6:30 am. Are there private drivers who can take us to the airport at 3 am (or earlier) if need be from Ravello? Is that doable at that hour? I don't mind leaving early in the morning. Just want to ensure it's feasible.
