Bit of a variation I know, but looking at having a night away soon with the dc and can't decide where to go.
We've done London before but not for years, it would just be sightseeing, Hyde park, eating out, a night or two in a hotel.
Never been to York but have always fancied going, not really sure what there is to do with dc though.
Other option is Chester Zoo and then checking out anything else in the area.
