A teenager from Barry was killed in Magaluf when he tumbled 70ft from a deadly apartment block walkway.
Eighteen year-old Thomas Channon, is the third UK holidaymaker to die in the same apartment complex this year in a series of falls.
Spanish police said he fell from a balcony - but friends say tragic Thomas tumbled from a deadly walkway after he stumbled over a wall.
His body was found in the gardens of a the private apartment block Eden Roc by a gardener on Thursday morning.
Thomas of Rhoose, near Barry, was on his first ever holiday with friends to celebrate completing his A levels.
His father, business consultant John, 67, and midwife mum Ceri, 49, are understood to have flown to Mallorca.
Last month 20-year-old Tom Hughes from Wrexham, died at the same block.
Parents of his heartbroken friends have now brought their own sons home from Spain - and demanded action over the low-walled walkway.
One mum, who asked not to be named, said: "We went to where Thomas fell and the wall is way too low. It's about knee height.
"When you look at it there are loads of trees and bushes beyond the wall which gives the impression there's a garden, but there's actually a 70ft drop.
"Something has to happen now. It shouldn't take all these kids dying to make sure proper precautions are in place.
"The caretaker who found him was crying to us saying 'this cannot go on, something has to change'.
"But the hotel has done nothing to tape off the walkway or put warnings in place.
"Three kids dying here this year is just unbelievable. We're furious. There are kids going out tonight and nothing is being done."
She said Thomas has wandered away from his group of school friends at around 4am on Thursday morning and had entered the Eden Roc apartment building which was next door to the Hotel Florida where he was staying.
Police believe he may have got lost as he made his way home.
Neighbours at their four bedroom family described the family as “lovely” said Thomas was a "very polite" young man.
One neighbour, who did not wish to be named, said: "We do not know what has happened but it is very sad.
"They are such a lovely family and always very friendly and always say hello.
"Thomas and his brother are lovely boys and always very polite.
"It is just so sad."
Another neighbour said: "They're lovely neighbours. Really good people."
Thomas is the third British holidaymaker to have died in a fall in the Eden Roc this year.
In April bar worker Natalie Cormack West Kilbride, Scotland, fell from the Eden Roc apartment block after reportedly trying to edge her way along an overhang after she discovered she didn't have keys to get in.
And last month Tom Hughes, 20, of Wrexham, North Wales, died at the same block.
