The Summit at Snoqualmie is a great place for the family to ski. Yes, it can rain here, but if you found this site, you know the weather before you go. Summit West is mostly a beginner to intermediate hill and yes, people are learning to ski here. Yes, people sometimes miss a chair fumbling to get on, just you used to do. There is some good steep terrain on Big Thunder. Summit Central has a legit terrain park, some terrific steeps off 360 Chair, and some mellow areas for the kids and beginners. Not finding challenging terrain, go try Alpental. While not the biggest area, there is some extremely challenging terrain off chair 2. Yes, sometimes the powder is more moist than in Utah, but that is why K2 invented wide skis, get yourself some mid-fat or full fat skis and tear it up.
