The site you should go to is at Gordale Scar, the most stunning site in England..avoid weekends if you can in the middle of the season.....The site in Stainforth is ok, but doesn't hold a candle to Gordale scar if the landscape is important to you........
if you go to knight stainforth you need to know that the tv reception is worse than poor . we couldn't get a picture on any channel. it was dire at night with no telly.
Hope you have a good trip, we go at least once a year now, I first went as a little boy in the 60's and apart from being busier at weekends it hasn't changed.....
