I don't know if I agree or disagree but I just accepted the fine would be the consequence of taking DD out of school in term time, in a "all actions have a consequence" kind of way. I figured that I'm an adult and can measure up the pros and cons of my own child missing school and act accordingly.
We took DD out one week before the Christmas hols began to visit my parents in my home country. The extra week had nothing to do with it being cheaper, we just feel 2 weeks is not long enough for the distance we're travelling. My reasoning included the type of activities they do on that week, how well DD had been progressing at that point, how many absences she had. We sent a polite letter to the headteacher and she never replied so we have no idea if she had even seen it. We fully expected to get a fine but we didn't.
I didn't expect any extra teaching resources or support to be given - quite opposite, actually, I expect that I would be responsible for any catching up she needed to do. As it happened, DD got double homework on her first week back and as far as I know, that was it. We just got her report last week on parents' evening and she's already achieved the expected outcome for end of year, so it did her not harm, which doesn't mean it wouldn't be harmful to other children.
