Anything interesting happening today? Wanting to pop up with my nearly 4 yo DS for the day, no buggies involved so can do pretty much anything !

London Transport museum
Diana Memorial Playground

That's exactly what I was thinking but just wondering if LTM will be too busy

Ours loved 'driving' the DLR, then there's a nice playpark at Greenwich. All free!
