Hi Julie,
Yes it definately is stopping me taking my van to the south of France and Spain this year. I usually tour for three months per year,(three seperate trips due to work commitments). Our last trip was to El-Delfin Verde on the Costa Brava last August / September for the best part of four weeks and from door to door it cost us around 2500 pounds all in for two people which I do not consider is value for money.
I am now only restricting the use of my van to the UK for long weekend breaks etc..
We have now reverted back to flying abroad using the cheap airlines and then renting good quality self catering accommodation which for our next trip to Lanzarote works out at half the price I paid last year for the same duration. This year as you quite correctly say, with the strong Euro, touring abroad with a caravan is going to be even more expensive. It's a great shame but if I do have a change of heart and decide to tour abroad with the van again, my choice of destination in Europe will be much closer to the English channel than before.
