As an elementary school teacher of over 40 years - yes do it. I have seen that children on vacation with their parents gain so much in the time spent with their parents and family. It gives them a broader view of the world and other people. When my 4-5-6 graders went I even refused to give them work, other than a pleasure book to read. It is their vacation also they need to enjoy it, and I can catch them up when they return. That is my job.
