jo-anne,
Have you ever thought of using the cl`s in the lake district? there are lots with elec hook up and loos some have showers,
They have the same views as the big sites at a fraction of the cost, and the owners have a lot of local knowledge.
One I`ve used quite a lot is :- Mrs Cooper, Upper Hawthwaite Farm, Broughton in furness,only a short drive from Coniston Water, It`s adult only, ( I don`t know if that affects you) but you can wake up to Stickle Pike out of the window,an exelent pub The Blacksmiths Arms is about half a mile, they serve great food and lovely beer.
Good luck.
Tony A
