Well if you have to work for the resort, I would lean towards the rental tech, (at least you get to work with equipment and maybe learn some stuff), or retail cashier. You can stay inside, nice and warm, then go ride for your breaks.
The other job I would look for is the on mountain restroom attendent. Yeah, you got to clean some bathrooms, but only shit you have deal with you can flush away. The guys who do that at resorts around here, carry a backpack with extra toilet paper and ride all day long. Going from spot to spot. Part of the job is to bring TP to stranded tourons who have ran out. Just a thought. It can be a popular job or not popular depending on the scene.
