Slight note of caution if you are heading there over half term, or probably any time in next few weeks. There is a timed ticket system for the new First World War exhibition at peak times, which we found was 2.5 hours from our entrance time. We did eventually manage to go in earlier than our allocated time as we had other things arranged for the afternoon but otherwise you have to wait even if there is no queue
or go after 3.30pm. The museum itself was very busy but the war art gallery on the 2nd floor quiet if poorly signed. However the new gallery was definitely worth the visit, evocative and informative, although quite a lot of exhibits in a small space.
