What makes a family event feed actually useful?

I'm a dad of three, and the hard part of weekend planning was never a lack of event pages. It was having too many calendars, incomplete details, and no quick way to narrow the list to what fit our kids. I built TakeTheKids around that problem, and it launches here tomorrow. If you plan outings for children, what detail helps you decide fastest: age, cost, distance, indoor or outdoor, or something else?
