We are looking for something non traditional and low on the budget scale

We will already be married earlier in the year and just looking for somewhere to have a party for our family and friends but looking for somewhere that is ours for the night. After the party we can have a fire and hangout without having a time limit that says "everyone out" and also somewhere where guests can stay overnight, camp or stay in the place that we already paid for. Places that we have looked up have been camp grounds, kids camps that are out of season, or renting a house on big grounds. We are having such a hard time finding this needle in a haystack type of venue in upstate New York anyone have any ideas
