YES I would, and I have!

One year I approached a (fairly local) historical trust homestead and asked whether their education team would come in on a Saturday and run games/activities for a small group of kids. They did, and we basically had the run of the house, complete with and activity-based tour and "old fashioned" games (knucklebones, quoits, sack races, etc). They had a (v. expensive) cafe on site, but I sweet-talked the owner into doing a basic spread of mini-pizzas, patty cakes and drinks for a song. In the end it came out near $300 for 12 kids (most of that was paying the education team), but my DH was away o/seas and I was pg with bad SPD and it was the middle of winter, so it really was a fantastic innovative solution because I couldn't have put on a party. I'm not sure DD fully appreciates the uniqueness of the experience, but I'm sure she will one day!
