Price of staying on a site

Hello this may sound contrivercial, but I have been reading on the site about how expensive things are getting in the club, I have been looking at the prices of the sites and the most expensive ones seem to be at the most £25.00 per night for 2 people, where you can get ones for £11. In the real world I do not think this is expensive, try and book a B&B, Hotel, YMCA for that sort of price (price was looked at in peak times). Both provide electricity and facilities such as showers and toilets and your own area to go (the van), the only difference is you choose to take a caravan rather than staying in a brick room, which I like as all the bedding etc are my own. What does everyone else think?
