Bansko is a great destination for kids and they have a junior ski club but I don't know from what age they take them in.

there are some realy good resturants about, both traditional and pizza, more british as well very cheap. Not sure what there is to do for Kids of that age but after a day on the slopes, they are usually quiet tired anyway
if you need any help give us a shout
