At the beginning of this thread you said that you and your husband wanted to experience your nephews first WDW trip with them. I love taking people to WDW for the first time, it always renews the magic for me. Because I figure that I am getting this bonus out of the trip, I can be more flexible about when I go. If you really don't think you are getting the advantage of the joy of family with you, then take the hard line and make them go when you want or stay home. As a jr. high teacher in an affluent area, many of my students are taken out of school each year to travel, sometimes up to 4 weeks at a time. Parents do need to realize that when children are taken out of school, they do miss out in one area, but gain in another. When my students go to WDW, I always give them assignments that focus their learning on the topic we are studying in science and have them learn where they are. What parents forget to realize often is that when you make this choice, usually your childs grades will suffer. While you understand this while you are excited about your trip, this understanding is lost when the report card is issued and your child misses the honor roll.
