I find this really interesting because I taught in Public school for 12 years and I don't think anyone ever asked permission to go anywhere. I don't think that I had any right or the principal has any right to tell you when you can take a trip. Really, all trips are educational to some point. I always told parents that it's just going to show up as an absence on the report card and it would be listed as an illegal absence in the permanent folder, but there wasn't any consequence. We had kids who would take a month off, to visit family in another country and it was all illegal, but they weren't retained or failed. There is a huge difference between a trip and just not coming to school. I'm sure he is trying to encourage parents to take trips during school breaks, but he has an odd way of going about it.
As a teacher, I really didn't like kids missing because no matter how hard I tried, I couldn't give all the work we did to take on the trip and most parents didn't do it at all. One of our teachers just had the kids keep a journal instead of preparing all the work. I would just go, ignore the principal and have fun. What can he actually do to your kids if they aren't failing in their classes? You might want to speak to the teacher and see what he or she would like done during the trip.
