Three months worth booking

The same year of measurements, decided rather than tabulated. Each opens the map below on dates in that month.

How busy it gets

Osrednjeslovenska records 5.6 overnight stays per resident a year (3,164,426 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.
