Cost of sites has gone mad

For about 13/14 years we have stayed at North Yorkshire Moors Site.  Its one of our favourite sites on the network and perfect for our family.

Ive just been looking for the end of May as its half term for our kids and was almost floored when i saw the price.  

This is a site which is lovely but has no toilet block. 2 Adults, 3 Children £36.70 per night!!!! When we first stayed there it was £18 i believe.

I then checked scarborough west ayton which we also like and stayed there last year - £60.20 per night

We thought the price we paid at easter at Gwern y Bwlch was bad enough but this is now a complete joke.

We have stayed in a lovely small site only 500 yards up the road, with the best views in whitby and a toilet and its only £18-20 per night.

Do the caravan club actually want anyone to keep with them.  We've been members for 15 years and i am pretty close to leaving now as its just unsustainable.

Do they want families or are they actually just want older couples with dogs to visit their sites and create an exclusive adult only and dog club? 

Im aware the cost of electric etc is rising but not surely by that much!! 

Anyone else think the same or am i just going mad
