We are thinking of \link{http://www.les-tours.com\here} in France. Although Eurocamp go there it is about £1100 for 12 nights in high summer, doing my sums and taking our own tent = £450 :) This only problem is we want to buy electric and fridge, which will mean roof rack/roof box. But I reacon that will be about £200 ish.
Do you all approve :)
