Sometimes if you want to go away with your children term time is the only way to do it
^ However that is a choice. It's not a necessity to go away on holiday, it nice but you can live without.
If you make the choice to go away in term time you have to suck it up and pay the fine, and calculate this into the cost of the holiday.
We choose not to interrupt our children schooling so we only go away when all the children are off school ( a choice of 3 weeks in a year) or we don't go away at all.
Even if we cannot go on holiday we still fit in plenty of fun family bonding days and we will have weekends away.
