It is a well-known fact that holiday firms ramp up the price of a family holiday as soon as the schools break up, with many boosting their prices by up to £1,000.
But it seems for many Brits, the warning letters from head teachers and the threat of a £60 fine are not enough to deter them from taking advantage of term time prices.
In the survey of prices by the Nationwide Building Society, a family holiday at Center Parcs during the school holidays was found to be £890 more expensive than it would be during term time.
A trip to Disneyland Paris was also bumped up by £400, while taking a family package holiday in Spain would during the official school holidays was increased by more than £1,000.
Nationwide's direct of banking, Graham Pilkington, told the Daily Mail: "With the current challenging economic environment, it's no wonder that families are looking to shave their holiday costs."
Mr Pilkington advised parents to investigate retailer loyalty schemes that offer money-off vouchers on travel, or to use price comparison websites to good holiday deal without disrupting the school term.
