Hi we are looking at a little UK holiday in August (fingers crossed) we have been to many Haven parks. Some we love and some not so much. I am currently looking at either Haggerston Castle or Berwick. Has anyone been to both or either who can give me a review. We are looking for somewhere with things to do in the area, activities on site, decent indoor pool if possible, direct access to a sandy beach but most importantly a nice CLEAN park with friendly staff :) Thank you
