K.B.
I skied Taos NM years ago and adored it, but can't speak to kid friendly since I was in high school. In colorado, Beaver Creek is a fantastic family mountain, tons of green and blue runs for everyone. There is also a children's museum in the village, ice skating, and an adventure mountain for tubing and stuff. You can stay down in Avon, the town below the ski village, and take bus shuttles up to ski. I would check VRBO, much better to have a kitchen than have to dine out.
