It's still cheaper to go abroad for accomodation and spending money even with the flights. We went on the east coast for May bank holiday weekend and spent more than going to Lanzarote for a long weekend.
£1500 a week for a caravan in Cornwall this summer!
We're paying €1200 (£1038) for a 3 bedroom, 2 bathroom villa with own pool, on the beach. We'll BBQ and have picnics on the beach and round the pool, much cheaper than UK, especially when sharing the cost. Going outs cheaper too, €3 for a glass of wine compared to £6 here.
Definately get more for your money and the good weather, although it's been good here lately but it don't last.
