Visiting local museums when taking a cottage break

Remember when visiting a new area that local museums can be a real mine of information.  Many contain fascinating photos and more.  One great bonus of going away in the UK is that a good number of museums offer free entry still, although local museums may need to charge a small entry fee.  Also remember that by visiting these places you are doing your bit to support the community.  If you are taking a self catering break in London you will be spoilt for choice when it comes to museums.  There is so much choice.  There are so many to explore and so many fascinating things to see.  Remember if you have any tips that would help others, let us have your feedback.  We love to hear reviews and recommendations.
