If you go to Camden - I highly recommend the "The Swan House" B&B (Lyn & Ken)- probably the nicest owners my wife and I have ever met. It was as if we had known them our whole lives. In January it is very peaceful and beautiful up there.
On a seperate idea: get her a nice leather Coach hand bag.
My wife has a couple and they are built like tanks - she hasn't destroyed one yet so that gets the two thumbs up! Lots of funtional designs and styles.
How about a piece of gorgeous blown glass?
See Eben.
You are a lucky man to have a wife like that, Mr. Sandman!
