That's a good point if somebody is in the area for a week. But the OP is only there for 3 days. Giving one out of 3 to Bridger vs. Big Sky for a family of low intermediates is a marginal call IMHO. Especially during late March. It doesn't matter how conditions compare to Minnesota; it matters how the areas on your trip compare to each other.
I've read this comment before, though I know nothing about it personally. If the OP is interested in lessons for some or all of his family, that would be the best reason I've heard to give Bridger one of those 3 days.
