We used to apply for 5 days each year, when eldest was little, and were always granted it. Head used to say family time was important, and we had zero money.
Since the changes, and now eldest is at secondary, there is just no choice.
And no, I don't agree to spend longer saving up. £1000 or more for a week away in a caravan in the U.K., isn't worth it. When you have little funds, you can justify a £300 trip, but to pay £1000 for the same, better spent on essentials for us/kids.
So either we get a miracle cheap bargain during term time, or no holiday.
