I think the sad thing is, is that there will be families, single parents, low wage, no car, who just can't afford term time holidays at all. Sometimes it's not a case of just saving up.
I didn't have a holiday for 7 years, and while it's not a right, it really did affect me. We are not in the 'can't afford anything at all' camp, but we have struggled. We live in a deprived area and I know of people who have collected the voucher for a Sun type holiday only to realise they can't actually afford the expanded price of food when they get there, but they don't have a car so can't take food with them.
HOWEVER, my dad has asked me to take my three boys out of school to take them on holiday - for two weeks, over half term. I won't be doing it because one week is enough fgs when you're going short haul! A 2 week jaunt is not required.
