I'm working in London for 2 days and will be bringing 2 16 year olds to spend a couple of days. They've been to London a couple of times a year, but it's the first time they've had the days to themselves. They're not really interested in shopping etc. Although do like a good rummage in a charity shop, but not in the v expensive areas.
They want to go to the Hunterian Museum, any other similar places I can suggest to them? They're happy to get the tube and bus and explore.
