Oh boy, so many choices. But since you're asking this on the Denver page, I assume you've narrowed it to Colorado resorts (though I'd also suggest looking at Utah, in particular Park City). Take a look at Away.com's ski guide, which includes recommendations for the top family resorts, where your kids can learn to ski as well as enjoying snowy fun like tubing, snowshoeing, and sleigh rides! http://away.com/skiing/
