Police stopped the tourists at Stackpole in Pembrokeshire – where they told the drivers to return home.
Police Community Support Officers (PCSO) were subject to abuse from the motorists, who were issued fines and sent home, says the Pembroke Dock Police.
A spokesman for Pembroke Dock Police said: "Thirteen people came from West Midlands to Stackpole.
"They decided to be abusive towards the PCSOs instead of returning home when asked, with assistance from response officers they were issued fines and sent home.
"One vehicle had no MOT either – you couldn’t make it up."
