Wow Biggarmac that is a great price!! I must look in the wrong places because I have never managed to find sites for motorhome, hook up and 2 people for less than about £26 upwards.
We joined both the main camping clubs mainly to benefit from cheaper stays on sites. However, even with the discount, it is still too expensive to do regularly. I know it is cheaper than staying in a Bed and Breakfast but it is far more expensive than we had thought it would be.
It is frustrating when you see 'from' £8 per night.... but actually, for a motorhome with hard standing and EHU for two adults and two dogs, then VAT , it is still usually £26 - £30 per night. Even when advertised as half-price midweek, in effect it is only the pitch price that is half price but then still about £8 per person on top, then the dogs, then EHU then Vat so the saving is not half price at all, you save about £3 quid only off the total price.
We try to mainly wild then go on a site occasionally.
