A family were left disgusted when their 13-year-old daughter discovered a crack pipe in their rented caravan.
Kasha Reed, 29, and partner Abigail Brown, also 29, took their six kids on a break to Haven's Blue Dolphin Holiday Park in Filey, North Yorkshire.
Kasha's nine-year-old daughters Kyanna Tuplin and Ava Greer spotted something on top of the wardrobe in their room.
The Examinerlive reported how their older sister Jaymie-Leigh Reed, 13, pulled down an enormous crack pipe and a glass jar containing a "substantial amount of something".
The kids didn't know what it was, but suspected it was dangerous and took it to Abigail.
She complained to the staff at the site and was given a full refund.
The discovery comes despite Haven introducing new cleaning promises during Covid-19 pandemic.
Kasha, a supermarket customer assistant, from Barton-upon-Humber, Lincolnshire, said: "My kids could have lost their lives. Luckily, they knew not to touch it.
"The amount in there would have killed me at the age of 29.
"I'd gone to pick a pizza up and it was Abigail that was there, I came back and I couldn't believe that's what she was holding.
"It was unbelievable. If my three-year-old had got hold of it, lives could have been lost. It's really quite serious."
The family, including 12-year-old Lilly Smith, 11-year-old Teigan Reed and Harry Humpleby, three, booked the three-night stay at the holiday park.
The kids had missed out on socialising with friends and lost time in school, and Abigail had lost her job in retail.
The discovery was made late on the final day of their three-night getaway last month.
Kasha said: "My two nine-year-olds were stood on the bed and they asked my 13-year-old what was on top of the wardrobe.
"My 13-year-old got it down and it was a crack pipe, with a substantial amount of something in a glass jar."
She called an out-of-hours number and received no response and then then drove around the site in searching for the security staff.
When a guard was eventually located, he was dealing with a separate issue so the pipe was hidden in the caravan for the night, they said.
Kasha was issued with a full refund following the incident and also offered a 50% discount on a future Haven booking.
A spokesperson for Haven said: "We are sorry for the experience of the Reed family in relation to their recent stay at Blue Dolphin.
"Despite the strict cleaning measures we undertake, some drugs related materials were hidden at the top of a wardrobe, which the family located when they stood on the bed.
"We are surprised that any guest would look to have such items on our breaks but would like to assure all guests that we take such incidences extremely seriously and would look to remove the offending items immediately.
