Boyne is fun. I don't know how the lodging is there but you should have a good time.
Another Michigan local here, go Boyne. There are two mountains about 40 minutes apart and I believe the lift passes are usable at both mountains so if you get bored of one you can go to the other.
As others have said, the Midwest is not exactly a "powder" destination but Boyne does tend to get some good lake-effect snow when systems roll in from the west over Lake Michigan. They might get 150" of snow in an average season which is half of what you'd expect in Colorado's front range, but the season is also a month or two shorter, so it's not all bad.
Both mountains about 500 vertical feet which is large by midwest standards but small by everyone else's standards except for indoor fridges and dryslope
Good variety of terrain and parks, although not much in the way of "extreme" terrain.
