There is a fantastic holiday park in worcestershire, my cousins were telling me about it when they returned from their holidays at the park.  They said that it was just he best place to take a family as it was very family orientated and geared to entertaining families.  There were 3 different kids clubs which catered for different age groups and organised activities and events suitable for those ages.  It gave my cousins a bit of time to enjoy some time alone.  The kids loved the swimming pool, which had some slides on it and they made plenty of new friends.
