Swap Lisbon for the Algarve, Zadar for Porec, and Ibiza for the Costa Blanca if you want to save money on a beach holiday this summer. This is the verdict of the Post Office’s annual investigation into the cost of holiday staples around Europe.And with the pound down nine per cent on the same time last year, and uncertainty surrounding the UK’s departure from the European Union likely to hurt it further, British holidaymakers’ hunt for value might never have been tougher.Sunny Beach in Bulgaria has again – for the fourth year running – proved to be the cheapest destination surveyed by the currency experts, with a basket of tourist staples, including a cup of coffee, a bottle of beer and a three-course evening meal for two with a bottle of wine, coming to just £37.33. But it is the idea of changing one destination in a country for another offering a lower cost that could be more appealing.

Porec on the Istrian peninsula in Croatia would save a couple – eating out each evening for six nights – £180 over the same in Zadar, farther south. Spain’s resorts provided yet greater differences. The Costa del Sol was ranked the third cheapest destination, with a basket of items costing just £60.65. A meal out costs just £28.61, according to the Post Office. At the other end of the spectrum was the Balearic island of Ibiza, where a meal costs £65.52 and the total comes to £131.02, more than twice that of resorts on the Spanish south coast. The Costa Blanca ranked sixth overall (£75.56) and Majorca 12th (£88.98).The Post Office also found that a fall in resort prices around Europe would help mitigate the damage done by a weakened pound. Compared to five years ago, costs in the Costa del Sol are down 21 per cent, 15 per cent in Porec and 9 per cent in the Algarve. Sorrento in Italy and Nice, France, have seen the steepest rises since 2012, 61 per cent and 44 per cent respectively. The Post Office highlights how staying in the Algarve, the second cheapest destination surveyed and boasting golden beaches framed by wrought limestone rocks and sensational seafood, is nearly half the price of the Lisbon coast. The former’s shopping basket cost £58.88 next to Lisbon’s £99.33.“If you haven’t already booked a holiday, do your homework to find a resort which best fits your budget,” said Andrew Brown, of Post Office Travel Money.
