Hi Rob, we stayed at Stanmore at Easter in 2005, it is a really nice site with good facilities always immaculately kept, they did have a adult only part if you don't have kids and are that way inclined, we were on a grass pitch and it did get a bit soggy. Beware the wardens were a little protective bordering overzealous on Bridgenorth is a nice little place and there is enough to keep you occupied for a day or so. The Severn valley steam railway is close by and worth a visit.
Hope you enjoy your stay.
