Hi Peter
There's
Lickhill Manor which is in Stourport, I haven't stayed there myself but it has touring pitches with ehu
There's also Yew Tree Farm, Pound Bank Bewdley, a reasonably priced site with ehu next door to The Plough which serves excellent meals and offers a carvery.
The toilets / showers are in serious need of an upgrade on this site and pitches near to the road can be noisy.
By far the best caravan park in the area is
Stanmore Hall but it closes from 4th January until 12th February
