More than 166,000 people have backed the petition to stop travel companies raising their prices during school holidays which has triggered today's MPs debate.
The online campaign received a huge boost in support after a Facebook post by an angry parent complaining about being "ripped off" by steep rise in holiday prices outside term time went viral.
Paul Cookson, 41, said he was "sick to death" of the practice after being quoted £999 for a holiday that would have cost £699 during the school year.
Stewart Sutherland says people need to take children on holiday in term-time to save money and also because of the difficulty of taking leave during school holidays.
He says life is short and will be difficult for young people so they should have as much family time as they can.
The Government has come out in defence of the UK holiday industry, after a petition started by parents frustrated at the extra costs imposed on family getaways triggered a Parliamentary debate.
A spokesperson for the Department of Business said:
The UK holiday industry is an extremely competitive market and as a result the sector relies on the profits from peak periods to make sure it can trade throughout the year.
On top of this, the industry competes internationally against companies from other countries and as a result may need to increase prices during these periods.
If anyone suspects that companies are behaving anti-competitively, they should present the evidence to the Civil Aviation Authority (CAA) or the Office of Fair Trading (OFT).
MPs will debate the extra cost of a family holiday after an irate parent started a campaign to stop companies raising prices when school was out.
A petition inspired by Paul Cookson's initial rant climbed to 160,000 signatures earlier this month, triggering today's 4:30pm debate in Westminster Hall.
Father-of-one Cookson initially complained when he realised he would have to pay an extra £300 to take his family on holiday in the UK when term had ended.
In his complaint, which went viral, he said: “I am sick to death of being ripped off with this country.
I choose not to take my daughter out of school term away on holiday and stick to the set school holidays - but why should I be penalized by doing the correct thing as a parent??? [sic]
