Since we started comparing prices of seasonal passes, here on the East of your East
in Lombardy, Italy, ski instructors can buy a regional skipass, valid for the whole season of course, valid on all ski areas of the Region, last season it costed 220 €.
The ski areas in my region range from
Barzio Piani di Bobbio (a v. small area) to Livigno, Madesimo, St. Caterina, Bormio, Passo Tonale...http://www.maestridisci.lombardia.it...aleMaestri.pdf
"Normal" skiers pay for the same 550 €http://www.anefskilombardia.it/Prezz...%20anefski.htm
At Madesimo last season, a full price day pass costed 30€...
Alas, I ski not only Lombardy but also Valle d'Aosta, Piedmont, South Tyrol and sometimes Switzerland and France, Austria (or have skied in the past and for this reason, could ski again there in the future)
A season pass which covers all the Alps is not avaialble....
