cycle route

Hi, hope someone can give me a bit of advice. Dragging my friend out for a swift 30 miles somewhere in the Westerham area on the weekend. It's neither of our regular stamping grounds but we require a circular route with either a pub at about the 20 mile mark or at the end for a rather nice lunch. Preferably quiet routes so we can tootle along and discuss marital break ups and her rubbish husband (She bought him a Cannondale which he never uses but there are other more significant crimes).

Has anyone tried out the online route planning and storage/sharing sites suck as bikely? Is there a best, biggest? Woud appreciate opinions.
Cheers
