Any Mom's not sending their DC to camp or any programs this summer?

We have decided not to sign Andrew up for anything this summer. We are going away 2 times this summer and my sister is coming in for 2 weeks. I just feel that it would tie us down too much. I am a little worried about our decision though. I am hoping that he will transition back into preschool ok.

Did anyone ever take the summer off and have no problems going back to school?
