Staying there
A hotel room in Italy emits about 14.3 kg CO₂e per night under UK Government 2026 factors, so a week adds roughly 100 kg — about 18.2× the carbon of getting there by rail from Rome.
How busy it gets
Napoli records 5.3 overnight stays per resident a year (15,749,028 nights in 2025). Comparatively quiet by European standards.
Eurostat, nights spent at tourist accommodation by NUTS 3 region, against resident population. Shown for context only — it plays no part in which destinations appear or in what order. Eurostat does not cover the United Kingdom after 2016, nor North Africa or the Levant at all, so this figure is absent for roughly a third of the destinations here.
