You get to do a bit of skiing in lift ops, but that job is ridiculously boring.
Park crew is sweet, because not only do you get a lot of riding time, you also get to enjoy all the hard work you put in by skiing it. Also you get to help decide how shit should be set up.
Patrol and instructor is sweet in terms of riding time also, however both of these jobs usually require a qualification.
No matter what job you do, you will enjoy a season working on a mountain and will meet tons of super cool people.
