Welcome to PASR happyjack!
For younger kids I would probably say that Sno would be a little better for them. Elk is pretty much just like their trailmap looks like, long trails and not a lot of beginner stuff.
Sno is broken down into an upper and lower mountain. The top part is mellow, relatively straight runs that increase in difficulty as you move across the mountain to skier's right (left on the trail map). For the more adventurous, or if you just want to sneak away for a little while you can drop down the North Face and hit the steeps down there which are always a good time.
