Their dream vacation turned into “a holiday from hell.”

When Michael, 35 and Paul Atwal-Brice, 41, flew 10 hours from England and shelled out nearly $13,000 total on a Disney World holiday with their adopted twin sons, they expected at least a clean hotel room.

Instead they arrived at a space covered in “so much crap and dust,” Michael told the Mirror. “You wouldn’t put a dog in there.”

The family’s room at Disney’s Caribbean Beach Resort hotel in Florida cost more than $500 a night — but the couple alleged it had exposed wiring, dead cockroaches on the floor, a film of dirt across surfaces and, worst of all, “a used condom on the bed.”

The situation was enhanced by the fact that Michael and Paul’s boys, 13-year-old Levi and Lucas, are autistic, epileptic and non-verbal — so they require more supervision than most teens.

“There was lots of exposed wiring. Our boys have no sense of danger, so they could easily stick their fingers in that,” Michael told the UK outlet. “The boys could have stood on the cockroach and could very easily have touched the condom if they dropped their bouncy ball down the side of the bed. That’s what shocked us.”

The married couple from Barnsley claimed they even called the hotel ahead of time, to ensure the room was cleaned, but to no avail. “We couldn’t stay in there. The boys were upset and were screaming and distressed,” Michael said.

The couple requested and received a new room — but they said the “dirty and dusty” accommodations still weren’t up to their standards.

“That’s what shocked us: We’ve not just booked any old hotel,” Michael said. “We’ve purposefully booked this resort and spent a vast amount of money to make it all magical and special. It’s supposed to be magical, once in a lifetime — but that was like a one-star bedsit.”

The couple requested a refund, but claimed they were denied. As the situation escalated, senior management moved the family to Disney’s luxurious Grand Floridian Resort and Spa.

In a statement obtained by Fox News, a Disney World rep said, “This family has received compensation from us numerous times over the past five years, and they continue to return. Regarding their current visit, we believe the guest claims are exaggerated, and again took several steps to enhance their vacation.”

The Atwal-Brices have fostered more than 20 children and have made a number of TV appearances discussing their tips and tricks for giving their kids a great holiday on a budget.
