Staying there

A hotel room in Portugal emits about 19 kg CO₂e per night under UK Government 2026 factors — a country average per occupied room, not this or any particular hotel. 7 nights in one room adds roughly 133 kg — about 27.7× the carbon of one person getting there by rail from Lisbon. Two sharing the room halve that share each; the journey does not halve.

How busy it gets

Alto Alentejo records 5.4 overnight stays per resident a year (563,312 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.
