A mum claims she had a 'holiday from hell' where amorous guests left 'sperm' floating in the hotel pool and dirty underwear hanging in trees.
Chelsea Stark says visitors also dumped used condoms in the foyer of the complex in Ayia Napa, Cyprus, which staff allegedly failed to clean up.

The 26-year-old forked out £250 for the week-long Thomas Cook break to the Pambos Magic resort, situated in the popular coastal town.
But she says she and her best pal were horrified when they spotted used condoms lying on the floor in 'public areas', apparently from 'the night before'.
She claims they later witnessed a couple having sex publicly in the two-star hotel's swimming pool after returning from an evening out.
She says they were disgusted to notice a white, cloudy substance - which they believed to be sperm - floating on the surface of the water.
Speaking to The Sun , Chelsea said: "The pool was white and cloudy. We didn't even dip a toe in it. There was no way we were risking that."
The sales advisor, from Glasgow, Scotland, had booked to stay in a self-catering apartment at Pambos Magic with her friend in 2014.
But she said there were 'no cooking facilities', only a kettle.
She also alleged that a British rep persuaded her and her pal into paying for three trips - but they only ended up being taken on one.
She told the news site: "For one – which was meant to be a beach BBQ – we were simply taken to the pool of another hotel. It was rubbish.
"She said the driver failed to turn up for another trip.
Chelsea added that the same rep later accused the pair of breaking a door and told them to 'pay up' - before revealing that he was actually joking.
And she said that as she and her friend went to leave the hotel at the end of their 'horrible' holiday, the manager refused to give them their passports.
'He allegedly told them they needed to pay for 'overusing' electricity by using a room fan, and only returned the documents after a 'long altercation'.
Thomas Cook gave Chelsea and her pal £50 each in compensation after they complained about the issues they had experienced with their trips and passports.
It is thought that the pair did not mention Chelsea's claims of public sex, dumped condoms and dirty boxers and thongs hanging from trees at the time of the complaint.
A spokesperson for Thomas Cook told Mirror Online: "We are always concerned when our customers are disappointed with their holiday.
"We apologised and offered Ms Stark and her friend a gesture of goodwill shortly after their return from Aiya Napa in 2014 which we are pleased they accepted.
"Since Ms Stark and her friend stayed at this hotel, it has undergone a major refurbishment to the rooms, pool and bar area and other communal areas."
However, Chelsea, who has a baby son, told The Sun her experience at the Pambos Magic resort had put her 'off party holidays forever'.
