A mum has vowed never to return to Butlin's again after a "disastrous" holiday with her son who is recovering from cancer.
Ethan Mullet, 11, fought medulloblastoma, a brain cancer which affects children, after he was mistakenly diagnosed with a virus in February last year.
He underwent an eight-hour operation to remove the mass before travelling to Germany for proton beam therapy, and later had nine months of chemotherapy in Newcastle.
The youngster of Denton Burn, Newcastle, was given the all-clear in March.
Mum Clare Mullett booked a four-night stay at the Butlin's resort in Skegness, Lincolnshire, to mark the end of her son's brain tumour treatment.
But she was left horrified when she allegedly discovered bloodied carpets and dead flies and woodlice scattered across the floor.
She said: "There was a seal on the door saying the room had been cleaned so we walked in and it was disgusting.
"It was covering in woodlice, flies and the carpets had blood stains on them. The sink was rotten too.
"I explained that Ethan had just been through chemo and there was no way we were staying in that room, even after being cleaned.
"I just felt dirty being in there. I started getting really itchy."
She complained to staff who pointed out the family had checked in more than an hour ahead of the allocated time of 4pm.
They steam cleaned the apartment, but Clare refused to stay there and the family were instead given alternative accommodation.
Butlin's has introduced a number of Covid-19 measures, including the need to book shows, craft activities and swimming in advance.
Clare told chroniclelive Ethan was left "devastated" after she was only able to book one slot for him to enjoy his eagerly anticipated spell in the pool.
She said: "Ethan had been really looking forward to going swimming.
"He loved the rapids and he was desperate to go back in. But we couldn't book another slot for him.
"We were told we'd have to wait in another queue and if someone did not show for their pre-booked slot then Ethan could go back.
"But his mobility isn't great after his treatment and who knows how long he'd have had to queue for before being allowed in so I just brought him away."
The 43-year-old also claimed customers had to walk to the main door of the resort's entertainment venue to order refreshments on the Butlin's app due to the poor phone reception.
The family had initially paid £2,200 to visit the resort in April but it was cancelled because of the Coronavirus pandemic.
Clare rearranged the holiday for £150 for four people when they were joined by Ethan's grandad John, 72, and sister Lily-Mae, 15.
But the NHS receptionist said she has been left bitterly disappointed by the experience and pledged to never return again.
"It has been a disaster from start to finish," Clare said.
"It was very cheap but it's not about the money. I'd never have expected it to be like this.
"I'd have been absolutely gutted if I'd paid more than £2,000 for the holiday we got.
"Ethan has been doing really well after his treatment. He was really looking forward to it as it was his treat.
"But our holiday was ruined. I was really disappointed. I'll never go back to a Butlin's resort again."
A Butlin's spokesman said: "We are sorry to hear about Mrs Mullett's recent break.
"We understand this was a very disappointing experience, however as the guests arrived prior to our 4pm check in time their room was not yet ready."
The holiday company added: "The safety of our guests and team remains our priority and we’d like to reassure guests that we have a strict cleaning and hygiene policy in place.
"Each room is thoroughly cleaned and sanitised before arrival. We'll be contacting the guest to discuss the issues raised in more detail."
