A father has won a High Court battle to overturn a council-imposed fine for taking his children out of school for a family holiday.
Campaigners have hailed it as a "victory for common sense" and say it could pave the way for parents to save hundreds of pounds a year - but is the difference in price between term time and school holidays really that significant?
In short - yes. For some destinations, the difference can be several hundred pounds per person.
ITV News examined three of the biggest travel companies - Thomas Cook, Thomson and Virgin Holidays - to compare the costs.
Via their websites, we asked each for quotes on a seven-night sunshine holiday for two adults and two children, aged 10 and eight; one at the end of May, one in July - the middle of the summer break - and one around October or November.
