Three generation short break

Could do with some inspiration. We are hoping to have a three night weekend break in the UK next year but inspiration is lacking. Six adults, three children between 3 and 13. Preferably under one roof but could split over two or I guess three properties. Either April or September into October. Concerns are to have enough bathrooms, something to keep the children occupied, for it to be comfortable but not ruinously expensive, a pub close by would be a major bonus. Have begun to look at cottages but wondered if a complex would be better. Would love to hear what has worked for you or indeed what didn't, always good to learn from others mistakes .
