Any considered insights gratefully received.
We're starting with a week in Jackson Hole and finishing with a week at Alta/Snowbird, but we have to make a decision on the middle week. Last time we visited Utah (Jan 2012) we skied at Snowbasin and Solitude, but not Powder Mountain (not enough snow to bother) and barely at Brighton, due to our child having lessons at Solitude. We're really keen to ski Pow Mow in better conditions (I doubt they could be worse than mid-January last year) and like the idea of exploring there, maybe with some catskiing as well, but also really liked Solitude (can definitely see the potential eg in places like Honeycomb Canyon etc, when there's new snow). We're not planning to fly all the way from NZ to ski only groomers, though if that's all there is, so be it.
Because of the Jackson Hole component this year, we only want to pick one in-between area -- not really big fans of just a day here and there at different places. We like to dig in for a bit and get to know an area. We'd stay on-mountain at Solitude, but somewhere in Eden, most likely, if we picked the other two. So far, points in favour of Eden: getting to ski at Powder Mountain and cheaper accommodation. And we enjoyed Snowbasin despite its limited terrain due to lack of snow. Against Eden: having to drive and cost of car rental. For Big Cottonwood Canyon: ski-in, ski-out/doing away with rental car. Loved Solitude, wouldn't mind revisiting Brighton too. Against: accommodation more expensive.
January is non-negotiable: that's the only time of year we can take a long holiday; as is Jackson Hole, because we haven't been before. Alta is also a certainty because we stayed at the Peruvian last time and loved it so much we can't not do it again, even if it means living on instant noodles for the preceding fortnight to be able to afford it. We have kids, one grown-up and one not so much, but they'll be happy with anything (as they should be!).
