Fraudsters are stealing around £7 million a year from British holidaymakers, according to a police report.
Scams include travellers receiving fake airline tickets, with flights to West Africa a particular target.
One couple were left more than £1,000 out of pocket after being conned into booking a holiday at Loch Ness at a romantic lodge that did not exist.
The report, from the City of London Police's National Fraud Intelligence Bureau (NFIB), showed that during a 12-month period more than 4,500 cases of holiday booking fraud were reported.
They included fake packages for the Hajj pilgrimage to Saudi Arabia and also for the Ryder Cup.
