K hope your not expecting too much from blackpool, we live only 60 mile away and in the ten years i have had a caravan we have never once been to blackpool it is a filthy disgusting dreary rip off place, if you insist on visiting take out a large loan and hide any young childs face as its the only place in england where you can buy a stick of rock and a sex toy from the same shop.
As has been said all the club sites are fine, personally i would stay in chester or southport, willow bank in southport is very nice as is the plassey which is not too far from chester in wrexham.
Liverpool is the city of culture but i have found it to offer nothing more than any other big city has to offer just loads of shops and chocking fumes.
