Staying near Iron Mountain
 

Long shot but I'm hoping someone will have some ideas here:
We're looking for a place to stay between Green Bay and Iron Mountain, MI in early January for a weekend. There will potentially be up to 18 of us - four sets of families but requiring 8 bedrooms or four two bedroom cabins. We'd like some sort of communal area where we can gather. I've looked on VRBO & Airbnb and have found some home possibilities, but wonder if there is a good resort area where we can rent a few cabins?
Ages of people are between 7 and 80, so if there are a few things to do that would be a bonus.

You might have more luck in the Michigan & Wisconsin Forums at Tripadvidor. There are many more users there.

Good luck!
