I worked at Stratton Mtn (also an Intrawest owned resort) for about 5 years. Benifits for me inculded huge discounts on gear (I worked in a retail shop) discounts retail wide (so other shops in the village) food discounts, free pass, and free lift tickets and discounted lodging at other Intrawest resorts. Usally, if I were to go to another intrawest owned resort, I would get 5 or so days of skiing for free, and roughly 50% off on lodging.
Needless to say, the place also 'got my foot in the door' of the ski industry and now I have moved on the bigger, better things.
So, with that said, I would reccomend getting job for any ski resort, you will get hookups and get to ski quite a bit.
