That's the #2 biggest negative in my book after the financial aspect. It's also why I don't own a season pass. I love skiing all over. I ski where the snow's best, I chase storms, I strike at last-minute lodging deals, etc... But that's a "too each his/her own" thing, and I imagine if you own a condo you're the sort of individual who likes the familiarity and comfort of routine, etc.. Or perhaps you want to make friends and acquaintances and enjoy more of a social aspect that comes with laying roots on one mountain, etc..
Way, way, cheaper.
the problem with renting and I agree it is cheaper, is that you aren't set with a place. We had a great house for 5 years until the owner sold, then we had a not so good place once (we are in no way high maintenance but this place had some bad stuff) before finding another good house. But you don't know and you have to move all your gear. Plus you don't have it for the summer/fall.
with regard to ski/in ski/out, obviously it's the best for skiing purposes, but we prefer having a bigger place off mtn for the same cost. Also, at least at sugarbush, in the summer, I'd rather be in the valley by the river or in town than being on mtn. So, when we do buy eventually, it will be off mtn.
