Hiya
We went for a weekend here and TBH there was not a lot to do.
We did find a lovely pub that had an old fashioned bowing alley that kept our boys happy for ages - its free and they do nice lunches there but can't for the life of me remember the name so not a huge help I'm afraid!
We went to a park in Winsford that was awful - full of broken beer and spirit bottles and dirty and just awful so I would avoid Winsford if I were you.
Beeston castle was nice and quite impressive - well worth a visit.
Depends how much you want to drive - Arley Hall is about 10 miles away and there is a nice farm and play area next to it open at weekends and Wednesdays I think. The you have Tatton Park, Dunham Park, Chester Zoo, Stapeley Water Gardens, The Blue Planet Acquarium...
