We had one family reunion that cost us the price of one main dish. We had about 80 people or so. I called our Parks & Rec dept and
booked one of the community parks in our town. It cost $25. It had pavillions, bathrooms, softball fields, hiking trails, a place for horseshoes.
Most of the people were from the state and some stayed with folks who had room. There weren't too many out of state people. It was held at the park for only one day.
For the last 4 years, my grown children decided they wanted to get together with all their cousins who are now spread over the country. We book a campsite, and we all bring tents (really camping and cheap) some have RV's and we go just for the weekend, so the ones who can't get off from work don't feel any pressure and can afford to come. Some come for Thursday night and leave on Sunday, some come on Friday and leave on Monday. We try to pick the same weekend, so those of us who need to take time from work can come. We had people last year
from PA, SC, FL and of course CT. The cost is about $100 for the weekend, as we all cook together and the campsite is cheap.
