you can also go skiing in the alps and keep the costs relatively low... of course most agencys offer holidays with 4 star hotels . they cost about 140€ per night, but in the top ski areas in austria there are lots of accomodations which are not in cataloques and cost from 30€ per night too.
one of the most beautiful ski villages is "obertauern" in austria. very very big ski area and very nice nightlife. if you dont take expensive hotels it will cost for 7 days about:
700 flight
400 hotel incl half board
170 ski card
= ~ € 1270 + drinks... going out... gear ( which you can hire )
with a typical 4* ski hotel it will be about 1800 or more...
