Don't you guys only have one season in Cali anyway?
I have heard from people that the snowline is indeed moving north, so head that way if you feel like there will be more or better snow.
As for working at a resort, yeah do it. There are 2 ways to go about it:
1) Play it safe and apply before hand, or show up at their job fairs if applicable. With this method you have less of a chance of getting hired, but there is not much risk to you. But depending on how late in the season that happens finding a place to live will be harder as the season gets closer. Then look at finding a place to live, people are always posting rooms or closets for rent because you usually gotta cram like 5 or 6 people into a 2 bedroom place to make it affordable. And people also post that they are looking for places to rent, so you can do that too.
2) Get a place to live first. Obviously there is some risk you won't find a job depending on your laziness or standards. But if your willing to do shit work like housekeeping and are persistent you will find a job probably sooner than later. Resorts are always looking for people because it's such a high turnover atmosphere.
Once your up there and working it's really easy to make connections to find better work, year round work, work for next year, and better places to rent in the future. If your planning to stay year round it might be tough if the resort is far from a town, but if you manage to get a summer job on hill rent will be dirt cheap and you might be able to continue living there for the next winter. Of course if the resort is close to town it's way easier. Usually your employer will either give you a pass (but take it away if you quit or get fired) or put you on a payment plan. But it's best to just get your own pass so no one can stop you from boarding if you switch jobs or get fired.
I've spent 5 years living at a resort and any shitty job or overpriced place to sleep is easily outweighed by the boarding. I have friends who stayed after I left and have moved up in the ranks and are doing pretty good now. One guy I used to house keep with was able to transfer to a bell hop position and eventually became the manager of the hotel, and has moved on to manage bigger hotels at bigger resorts. Now he's got a pretty good career out of it.
So in short just go to a resort you want to ride and live at and live and ride there.
