Their 'park-wide' parking permit isn't new, it's been around for many years. Any suggestion it was introduced to replace the Stanage sticker is completely untrue. (I gather someone from the PDNPA was trying to say that in response to protests at their withdrawal of support for the Stanage sticker - barefaced lie.)
Current prices are £40 a year for most of us, £30 if you're over 60 and £25 if you live inside the Peak park boundary:

I'm sure Offwidth is right, as an attempt to raise more money out of the Plantation and Surprise View car parks this will most likely turn out to be entirely counterproductive.
