Whose holidays land here

The markets this resort draws from, heaviest first, with the weeks their schools are off.

Brighter blocks are more of that week off school for that market; hover a block for the day count. The percentage is that market's estimated share of the resort's visitors.

The tourism figures for this country do not follow a ski season (peaks in month 4, April is close to the peak, January is near-empty), because they count every kind of accommodation and not just ski beds. The seasonal shape is borrowed from AT, CH, SK, whose tourism figures do follow a ski season. Only the shape is borrowed, never the level. No weather forecast was supplied, so weather is treated as neutral. Terrain size is measured from OpenStreetMap within about 6 km of the resort centre, so a large linked area can read smaller than it skis. This resort's lifts run 26 December to 21 March, so weeks outside that are not offered.
