Thinking of taking DS this week, we've done a lot of the London classics to death and this looks good but not sure if I'm being deceived by social media. Has anyone actually been? DS is almost 8 and very interested in history. Yes we've done natural history museum, v&a, young v&a, IWM, Greenwich, transport museum, the Tates, cutty sark, HMS belfast etc. Just looking at something a bit different but not sure this is worth the schlep out to custom house
