Heading to London at the weekend, DP loves history/ships/space so wants to go the maritime museum and observatory, Is it worth paying to go around/on the Cutty Sark, there will be Dp, Ds (6 y/o) and myself. Neither DS or myself really enjoy history type things and much prefer interactive/pushing buttons type places like the science museum and I'm wondering if DS will just get bored doing too much 'dry' stuff.
