Boyne is fun. I don't know how the lodging is there but you should have a good time.
Hey! You're from MI, right? I recognize some of the places in your signature. Pine Knob was where I learned to snowboard back in 2007-2008, when I lived in MI after moving to the US from the UK.I didn't like their patch program...literally took me 5 attempts on the 2nd lesson to get my freakin brown patch!
I've also been to Mount Holly.
The best place I've been to in MI is Bittersweet. It's a completely natural hill, bigger than Knob and Holly, and gets a crap load of lake effect snow from Lake Michigan. That place is awesome, bar far my favorite local place to snowboard at the weekends! You should go there some time!
