Stayed for 9 nights.  Excellent caravan site.  Pitches all hardstaning and sized as per caravan club rules.  The hard standing gravel does leave some grey mud on your awnings though - not too much of an issue.   Toilet and showers very clean and never queued or suffered cold shower - in fact the water is very hot - be careful of scalding.  Games room was made us of by our kids - pool and table tennis.  Great location, just 10-15 mins walk from Castleton.   Also not far from Hope.  Lots of walking opportunities from site - suggest going to Edale.  Lots of places to eat and drink in the village.  Had good meals at the George and the old nags head.  Lovely friendly wardens who look after the site so well - reception area adorned with loads of flowers.   Wardens were very helpful in extending our stay - coming to let us know that they had received a cancellation so we could stay longer.  Definitely would use again and recommended.  Note that there's no playground for kids, but that didn't affect us.
