New research by The Co-operative Travel has revealed that once popular resorts in the Western Mediterranean, such as the Costa del Sol and Algarve, are being shunned in favour of holidays in up-and-coming holiday spots.

The new number one area has been nicknamed 'the Mett' after its key destinations: Morocco, Egypt, Tunisia and Turkey.

This year Mediterranean resorts have seen a cumulative fall in bookings of 11.6% compared to the Mett’s increase of 23.4%. If these current trends continue then the two areas will swap places by the end of 2011, with the Mett becoming the number one choice for package holidays.

This would mean that by summer 2012, the Mett would be receiving over 38% of UK package holidaymakers.

Trevor Davis, director of retail distribution at The Co-operative Travel said: “The growth of all-inclusive deals, which appeal to people wanting to fix the total cost of their holiday, has helped to increase demand for these fast-growing destinations.

“At the same time increased capacity and the high cost of the Euro have both contributed to a significant rise in bookings.”

He added: "If these trends continue, it will represent the biggest change in bookings patterns since the boom of the package holiday in the 1970s.”
