Suggestions for second Normandy visit?

In Bayeux there isn't anything to
see other than the tapestry and a museum of embroidery.

I disagree.

The Bayeux cathedral is very worthwhile (see the vault, too).
See http://sophie-g.net/photo/build/bayeux/b_chev.htm and
http://community.webshots.com/photo/...9976wimXIquZYj
for photos that, while good, don't do it justice.

And the British war cemetary is an interesting counterpoint to the large
American one at Colleville-sur-Mer.
See http://web.utk.edu/~ablack/bayeux.htm for more info.

And the tapestry isn't something you want to rush through.
