Taken from their website:
Disclaimer: Fairy Park
You enter the Fairy Park at your own risk, and on the CONDITION that the owner or operator of these premises or their servants or agents for you have NO RIGHT OF ACTION against any injury to you or any person or loss or damage to any property. It does not matter how the injury, loss or damage is caused, even if it is caused by NEGLIGENCE or BREACH OF CONTRACT of the owner or operator of these premises or their servants or agents.
This really puts me off going there. I can't see this disclaimer holding up in a court of law, but it makes me question their attitude toward paying visitors to their park.
