Personally, I’m against parents taking their kids out of school for holidays. Nevertheless, I can certainly understand the temptation, and there’s an awful lot of persuasive rationale involved.
That said, what really annoys me is the part played by travel companies. The school-holiday price hike is accepted as a fact of life, but it’s blatant exploitation. If we’re allowed to have laws that stop parents taking their kids out of school, then why not one that stops this practice?
