If you choose to only limit yourself to where seasonhousing.com will take you, then i'd go with Mammoth or Val D'Isere. You dont actually have to leave Europe to get the things you want, on the contrary.
Like I said, Val D is a sick place, with arguably some of the best and most renowned pow skiing in the world. However it is in France, so accomodation will suck, but when you're young and doing a season, that doesn't necessarily matter that much.
If you're up for trying some places that seasonhousing do not cover, there is a multitude.
In America I would recommend looking into Lake Tahoe in Cali. It's fairly easy and cheap to find accomodation, and you have great parks and good pow all around you.
For Europe I would look at places like Mayrhofen, Serfaus, Kitzbühel, Zell Am See, St. Anton and Saalbach. Austria really has a lot to offer in both parks and pow, and accomodation is cheap and of high standard.
Hvis i har andre spørgsmål så bare spørg løs, jeg har prøvet lidt af hvert.
