Hmmm, I nicked this info....
"Just got back from austria yesterday and went snowboarding for so cheap. We were out at st gilgen which is a real quiet austrian village an hour bus ride from salzburg (BUS 150 TO BAD ISCHL)... It is a typical austrian village, really quiet but absolutely beautiful... met this austrian and they gave us the tip of getting the bus 150 to bad ischl and get off at STROBL.. From there you get another bus up to POST ALM.. It is 8 EURO for the bus ride and 20 euro for one day lift pass.. board hire was 15 euro ... hell cheap and great slopes surrounded by awesome moutains... there is so much snow up there at the moment, the most they have seen for 200 years... highly reccommend it.. im sure you could make your own party with a good crew.. accommodation in st gilgen was 40 euro a night for a double.. Hope this helps"Maybe worth checking out?
Chamonix and Tignes in France are wicked for riding but not sure what costs are like these days. If you could get a cheap flight and find a hostel to stay at it might be doable. I'm not sure what kind of budget you're working with...
The farther ahead you book the more options you'll have, especially around Christmas when hills fill up fast and rates go up.
Not sure if you've considered it but often self-service ( or self-catering) apartments can be way cheaper than staying at a hotel. We stayed in a beauty in Barcelona for half of what we would've paid in a hotel and it was fabulous! It's best if you're 4 people or more.
This link shows one apartment just as an example.
You can likely find a hostel too that might make it cheaper. Seems like you can get pretty decent rates for flights 'round Europe from the UK from what I know, so that's cool!
