Looking for facility sleeps 75-100 for a family reunion with kitchen facilities w/semi-priv sleep arrangements

basically central US for travel from Chicago and Louisiana. We have used group facilities at state parks for years, but now that we are older, are leaning more to some privacy at night instead of dormitory sleeping. We do our own cooking and would like a large central area (building/room) for dining and gathering. Our reunion is bi-annually and usually last 5-7 days.

We hold our family reunion every other year and use a church facility. We rent their pavilion and have a caterer come in to serve food. You might find a church hall that could accommodate you. What about a school? We stay in local motels (about 3 of them). Good luck!
