Just back from a weekend at Thetford. A very clean site with very cheerful Wardens. Services are limited, no toilet or wash facilities so need to be prepared to use the vans sites, Wi-fi and Van TV reception was very good. If you use the Three mobile network forget it, no signal for a few miles, which was lovely.  Nestled in the Forest there are some nice short walks and you can be on the coast (Hunstanton we went to) in an hour but Kings Lynn half an hour away.  Very quiet on this site, except for Apache Helicopters in the afternoon buzzing about for a few hours. Pitches were well spaced but no real space for kids ( which we don't have !) to be kids . Would certainly re-visit but as fairly new Caravanner's haven't found a CC site we wouldn't go back to.
