Pros: Terrain variety, fast lifts, grooming, economical if you're in the know
Cons: 1100 vertical, no tree skiing, overly manicured, crowds on weekends/holidays
I live an hour away and really appreciate Jiminy. For a small eastern area, it has a lot of variety: 3-4 legitimate steeps, a number of black/blue runs, and a bunch of easy groomers.
There's a resort/condo complex at the base that I ignore, but it does bring in the upscale "resort" experience. There are benefits: Jiminy has a super-quick 6-pack to the top -- 1100' in 41/2 minutes. But it also means they groom everything flat all the time, so there's little natural skiing unless you hit it on the day of a storm. The place is at the opposite end of the spectrum from, say, Berkshire East. Still, the place is well laid-out and very usable, and the trails are pretty and interesting for what and where they are.
The best part is price: for $45 you can buy a value card that saves $15/day on tix. It also comes with one day free. And they tend to offer internet coupons periodically for $25 or $35 day passes and "state" or men's/women's days. So, by picking the day, I often only pay $35 or $40 for an entire 8 hours (they're open 9 - 10pm most days).
Williams College is very close and so are other schools, so the average local's skill is pretty good. There's a contingent of telemarkers. On weekends/holidays, it does fill up with New Yorkers and visitors to the resort and I avoid those days.
Overall, Jiminy is a good miniature eastern resort. I'm a pretty good skier and I get bored if I go too often, but it's a very reasonable, closer option to southern VT areas.
