Need resort for family reunion

I am needing to locate a resort, other than Fin & Feather, on a lake that can handle 40-50 people with cooking facilities and lodging for a family reunion in mid June. ALL suggestions will be appreciated. Fin and Feather Resort on Tenkiller is,apparently, full. Time is of the essence. The resort can be in NE or SE Oklahoma. Please let me know ASAP.

There are some cabins at Eufaula cove. I can see if my mother can get me some info on them.

Might look at Robber's Cave State Park.
