A scheme to send two British police officers to party hotspots in Magaluf and Ibiza has been branded "a joke" by some tourists.
Two West Midlands Police officers are in the Spanish resorts dealing with victims and offenders from the UK.
But some partygoers said the officers were making "no difference".
The Foreign Office, which is funding the two-week scheme, said the officers would remind British holidaymakers to respect local customs.
Sgt Brett Williams and PC Martina Anderson, who arrived in Magaluf on Monday, are working shifts between 07:00 and 22:00.
PC Anderson told the BBC she had worked in the island resort "many years ago" and knew the area quite well.
They are spending a week helping the Guardia Civil in Magaluf, followed by seven days in Ibiza.
Cathie Wood, 46, a visitor from Nottingham, said the hours were "a joke".
"People don't even get out of their beds until midnight to come out and party. Where are they when... the trouble's kicking off?
"Two officers are like a drop in the ocean - they'll make no difference whatsoever."
Alex Patterson, 21, from Bridgend, south Wales, had not seen the officers.
He said: "We go out at 12 at the earliest and are home between four and six in the morning, which is probably why we haven't seen them."
Lee James, 22, from Manchester, who works at the City Lights bar, said the officers were at the resort months too late.
He said Magaluf was packed with Britons in May but since the end of July tourists were mainly Italian and Spanish.
He said: "I think it is a bit daft, to be honest. When would you ever see the Spanish police in England?"
Police from France, Germany, Italy, Portugal and Morocco have taken part in similar initiatives in Spain.
West Midlands Police has not commented on the initiative, but the British Ambassador to Spain, Simon Manley, said: "The presence of UK police officers will help to remind British holidaymakers of the importance of respecting local laws and customs."
