Thinking of visiting northumbria next summer.Will probably do a 2 centre hol as we would like to visit the coast and inland bits but are aware of the long driving distances between the two. We will spend a few days in alnwick first and then some more nr the wall. Can anyone recommend the best place to stay for access to hadrians wall and kielder ? Also which are the best museums on the wall and most likely to appeal to DS 4 and 8 yrs old ? Is kielder worth vsiting ? Both boys are quite 'outsidey' and don't mind walking etc. Thanks in advance, Louise
