I just got an email about a newly launced website and it looks fabulous. It's called Playplanit and it has listings of all kinds of kid-friendly things to do. No, of course it doesn't have as much fabulous commentary as Frisco Kids, but it has a lot more ideas. And a calendar you can click on to tell you where, when, how much...for any given day. Plus you can search by location, activity type, timing, age range, price etc.
Let me know what you think!
