I hear cannonsburg is OK during the week. Weekends anywhere in this state are going to blow goats, super crowded, long lift lines for short trails.
Otherwise you're going to have to drive a few hours up the US-131. Take 131 to 115 West past Cadillac and Crystal Mountain and Caberfae Peaks are about 30 minutes down the road. Caberfae can get pretty gnarly, they don't do a lot of grooming there and it's pretty low-rent. Crystal is really family friendly and has a full service resort & spa, etc., on-site lodging, dining, it's really a nice place.
More over in the Petoskey/Harbor Springs area (you have to take 131 to 66) there is Boyne Mountain, Boyne Highlands, and Nub's Nob. All pretty respectable by Michigan standards. A short jog off 66 (if memory serves me) past Mancelona is Schuss Mountain & Shanty Creek. Another good option, they're the same resort so your lift ticket at one is valid at the other and there is a shuttle that runs between them all.
