family-friendly...yesHaving taken my family to Alta every year since 1990, with occasional side day trips to Solitude, Snowbird, Brighton and Park City, I think Alta is very family-friendly. I have said this before, so I may sound a bit like a broken record, but both my girls, now in their young 20's, learned to ski at the Alta kids Ski School. They started at Alta when they were 4 and 6, and often had the same instructors year after year. Even into their teen years they wanted to go to the ski school because they had fun, got to cut the lines, and were taken all over the mountain. For the first ten years or so, we rented a condominium(s) with a large group of 10 to 20, all family (my parents, siblings, spouses and kids). We cooked our meals and generally entertained ourselves after skiing. Sometimes the olympics were on, other years the kids watched movies. We usually would invite some of the kids' instructors for dinner at least one night. If my wife and I wanted to get away from the family, we would walk over to the Peruvian (we also stayed there a couple of times, too) and stop into their bar. Usually, though, after a day of skiing, all we really wanted to do was go to bed so we could get up and do it again. Our kids were simply not interested in doing anything else, either. Eventually, our daughters managed to find their ways to Alta on their own on college breaks, and our oldest has now spent two seasons working there. Now we go there to ski and to visit our family.
...and the skiing has been consistently good to utterly fantastic.
