We usually do at least one or two after-school activities during the course of a school year (Mad Science, lego robotics, etc.). They usually meet once a week from 3:30-4:45, and then my son walks over to Kids After Hours in the same building until 5:30 or so when I come. It's been worth it for us for him to be able to do that kind of cool enrichment stuff. But they're usually only once a week for 8 weeks or so.
