I wasn't aware that they had introduced parking charges for members, that's not the current arrangement at any of their properties near us as far as I am aware.
What they have done is introduce the parking machines that scan your membership card rather than simply relying on displaying a windscreen sticker.
As I understand it this is because of how they determine funding for individual sites by visitor numbers, sites where you don't have to pay to enter, such as bits of coastline etc. can now gather visitor number info from these machines. Hence people wandering about with handheld scanners wanting to scan your card.
We're members and it's actually not bad value if you visit their sites frequently. We also use their campsites occasionally.
I think there were some chaps developing an underground tour down there that got pulled for some 'management' reasons too?
If they didn't exist what else would you do with elderly aunts on Sunday afternoons?
