Are CL's becoming too expensive?

The past few years have seen us paying around £15 a night on some 5 van(?) sites (both clubs) offering bumpy rough mown farm fields with electric and nothing else. Whilst I accept that owners need to make a profit, we have been told by a couple of site owners that nearby club sites charges £x but omitting the fact that they have heated toilet blocks, hardstandings et al. Going back to the original question then, is it us or are CL's getting expensive?
