I like the idea of a hard cap on 10 kids in the house. Any more and you put yourself in jeopardy of bad things happening. This is typically items breaking and pets bordering on heart failure... no damage to the actual children though. I'm glad I had a preview to the wonderful world of little girl sleep-overs. So far I only have experience with little boys... which actually works out a little easier since they basically play video games mixed in with the occasional dog pile session. If you can get through that with no injuries... consider yourself a winner.
