We're taking Ruby for a day out in London tomorrow, but looking for cheap/free things to do, as we're also going to the zoo on thursday so that's our budget for the week really. We've done natural history quite a few times before, and we missed the vikings at the british museum which was a bit of a shame. And I'll admit to not really enjoying the science museum too much.
So anyway, was thinking of the Grant Museum, which looks really cool, but wondered if anyone has been and if it's the kind of place you can spend quite a while or if it's more of a half an hour look and then we'll be done. My internet's shocking at the moment so it's taking me ages to search for info online but any other suggestions for free or cheap activities around that area would be gratefully received.
