Parents were left fuming after an inflatables fun day proved a big let down.

Around 1,400 people turned up for the Extreme Inflatable Bonanza at Crossley Farm in Mirfield on Sunday.

Youngsters were promised nine giant inflatables but there were only four or five – and the biggest one deflated and had to be blown up again when generators burned out.

Mum Tracy Ellis-Squire, 40, of Mirfield, who took along nine-year-old son Callum, described the event as a “shambles” and said: “We got there at 10.15am and there was hardly anything set up.

“Eventually it got started but then the biggest inflatable deflated and had to be blown up again. We were there for about three hours but it was badly organised and there was a lack of supervision.

“The inflatables weren’t being monitored and I thought it was very dangerous. There was hardly any staff and bigger kids were vaulting off it and pushing the younger ones out of the way.

“There were inflatables that were advertised that weren’t there and it was just very poor.”

The event was run by Mirfield-based Prestige Events & Party Planning and was billed as “the ultimate family fun day.” Tickets cost £5 for adults and £2 for children.

Stallholders paid a fee to be there and organisers were also selling sponsorship of the inflatables at up to £600 a time.

Writing on the group Mirfield Matters on Facebook on February 10 Mrs Victoria Wallin, who runs Prestige Events, said: “With a small amount of stalls available and over 4,000 tickets already sold this promises to be the event of the year.

She then listed the nine inflatables including The Jump Off, Bungee Run, The Mega Slide, The Mega Bouncy Castle and Total Wipeout Eliminator Simulator.

A ‘charity bubble football’ competition was also promised but never happened.

According to the Prestige Events & Party Planning website the organisers would make a donation to charity. The charity was to be chosen by the winning football team but no amount was specified.

A trader, who had planned to have a stall at the event, contacted the Examiner last week to express concerns over the organisation.

The trader said there had been promises that 3,500 tickets had been sold but there was no confirmation from organisers.

Kirklees Council also had concerns and a spokesman said last week: “Organisers did not let us know until very late in the process.

“We are in contact with them to ensure they have a viable plan for public safety, that any concerns are addressed and stressed that they are liable in the event of any incidents occurring.

“So far, we have not received a traffic management plan, no road closures have been applied for and we have asked for further details of arrangements regarding parking, food hygiene, secure inflatables, and first aid.”

Mum-of-three Mrs Wallin, who lives with husband Rory in Lower Hopton, has done much charity work after new-born twin son Louie fell seriously ill with a lung infection in December 2014.

Last year the couple raised £3,000 for two charities that helped, The Sick Children’s Trust and the Embrace Paediatric Intensive Care Ambulance Service.

Mrs Wallin, 27, was one of the organisers of a charity Christmas Market last December and in February the couple pledged to donate the £1,000 they won on TV game show Masterpiece to the two charities that helped save their son’s life.

On Sunday night Mrs Wallin issued an apology on Facebook which was later removed.

She told the Examiner she was “gutted and disappointed” and said parents had every right to be upset.

Mrs Wallin said people came expecting 10 inflatables but there were only “four or five” for most of the day. She said a generator used to power the biggest inflatable burned out and she had been let down by suppliers.

She said she needed to speak to the company concerned after the Bank Holiday and would contact all those who had complained.

Mrs Wallin said Kirklees Council had attended the event and was happy with safety measures. She admitted the experience had been a “learning curve.”

She couldn’t say how many tickets had been sold but said at least 1,400 came through the gates on the day. She also pledged a £250 donation to Kirklees Music School.

She added: “We are trying to sort it out and I will do my damnedest to make sure no-one is out of pocket.”
