Its been my experience that 6 or 7 year olds enjoy the kids programs about the most of all the age groups.
The activities seem to be a hit with them.. and at that age they are normally very social, and enjoy playing with the other kids. The face painting, scavengers hunts etc. seem to loose something for the 10 -13 yr olds.
Reminds me of the time I put a 200 piece puzzle together in 1 day.. and proudly showed Mrs. Kuki. She asked what was so special about that. I replied.... It says right here on the box 5 - 7 years <G>
