I have vivid memories of the British Museum from when I was a kid and we went on a trip to England. At the time I was geeking out about ancient Greece and Egypt etc and was in heaven seeing all those exhibitions. Also I remember forgetting my backpack in there and having to come back for it, and being passed from museum guard to museum guard to get to it. *g*

I was just checking out the website of the National Maritime museum, for some navigation and Age of Sail geekery. I teach part of a course on the history of navigation, so that would be very cool! But Kew Gardens, that also sounds appealing!
