Hi Kathryn
If you are put off by Scotch lad's description of the Wooler site perhaps you would like to look on the web at South Meadows Caravan Park. Although it is a private site the facilities are very good/excellent. Wooler can be visited if you wish. South Meadows is just outside the village of Belford (about 1/2 mile off the A1 - but don't worry the traffic noise isn't a trouble). It is situated about 5 miles in land from Bambrough and Alnwick, Seahouses, Berwick, Edinburgh, etc. are easily accessible.
Hope this is helpful.
