We did Broadway House at the start of the camping season (April). In April it was lovely as there were about 10 other people there, the site is massive though and I can't imagine going back in the height of summer. It was a very well kept site, clean, good toilet facilities, washing up etc. We didn't use any of the bar/entertainment/pool facilities because it isn't our 'thing' but they looked fine. I would go back off season again though.
Our normal camping places involve a field and a toilet block!
