A severely disabled boy is suing a theme park for failing to provide a suitable "changing places" lavatory.
Adam George, 11, claims Flambards Theme Park, in Cornwall, discriminated and failed to make reasonable adjustments for him under the Equality Act.
Changing places toilets are required by an estimated 250,000 people in the UK who need extra specialist equipment.
Flambards says it takes inclusion of all visitors seriously and has made adjustments to its toilets.
The company says a permanent changing places toilet would cost over £40,000 - an expense that could affect jobs.
Active lifestyle
Adam, from Redruth in Cornwall, was born with a genetic condition that weakens his muscles, affects his speech and makes him a full-time wheelchair user. He also has autism.
But none of this has held him back and he loves outdoor activities.
His favourite place for a day out is the nearby Flambards Theme Park in Helston.
His mother, Rachel, says: "He loves rides. He loves things that go up and down and move him suddenly.
"He can't climb, he can't walk, he can't jump, he can't run, so all of the physical sensations that are well known to be vital to a child's developments are out of Adam's bounds, so a theme park enables him to have so many of those vital experiences."
In order to use the toilet Adam has to be hoisted on to a table, then on to the loo. He then needs to be hoisted back on to a large changing table.
Converted horse-box
Rachel is a member of the group Changing Places, which aims to increase access for those who need the extra space, hoists and changing tables provided in these toilet facilities.
In the past 11 years, the group has successfully seen more than 1,000 of the toilets installed across the country.
Flambards, though, doesn't have a toilet with changing facilities suitable for Adam's needs, so when the family visit, they need to hire a Mobiloo.
This is a large converted horse-box with the space and equipment Adam requires, but it can cost up to £350.
