Silly site prices. Off season and peak season

I have looked at the latest handbook to book a site.  Prices are not clear ... There is no guidance, as there was in the past, as to off season / peak season pricing.  Is all pricing now charged at peak season rates? Go online .. No mention of differential prices as you book.

So the only way I can find how much a site will cost is to go through the booking process, then I will get a price, then I can decide if I can afford it or not.

for Example

I looked at the Bladon Chains site ... Page 149. A bargain at "from £7.90 a night, for one adult and pitch.  It's open from 01 March.  I decided to book from 01 March ... Surely this is must be low season, my experience tells me that this is the case. But I wanted too  book two adults, so I wonder how much this will cost??  Perhaps, at the very most, my wildest guess, at the most 2 X £7.90.  Perhaps £16 a night.  No it can't be that much ... The site has only just opened, so it must be off season.  Proceed to book it  £179.20 for 8 nights. £22.40 a night for 2 people!! There is no breakdown of the pricing on the email confirmation.

In the wildest imagination of consumer rip offs, "I could not believe it"!  How can you get from £7.90 to £22.40 by adding one person.  How do I find when I can go by myself for £7.90?

This seems to me the most opaque pricing structure you could possibly get.  I thought transparency was the new watch-word in consumer relations!

I booked, but will be chasing this up to find out WHY., The silly price declaration. (Would it have been cheaper to book 2 pitches with one person on each?). I don't expect I will get a sensible answer over the phone tomorrow.... But I have given the 'powers that be' a chance to formulate a response, in advance.

Watch this space!
