I think you echo most people sentiments.
Why pay for electricity/ shower blocks and laundry rooms if you dont require them ? And tbh I have no desire to visit club rooms and bars ala Haven, But thats just me.
I must admit I sometimes stop at the CC site in Clumber park (mid week discount) If I need to launder and sometimes it is nice to use the shower block etc, top up with a bit of electric and the hound likes the walking there.
The cost is £7.20 per night plus the cost of laundry
