Back home now. Nobody lost, no injuries. 
DS3 LOVED the bubble show, even if holding him sat down was like trying to tie an electric eel down with strawberry laces...
The older ones loved the launchpad.
They have asked to go to the Natural History Museum next half term.
Spag Bol heating through, feet aching (and the rest of me!), shame I missed those that were there, but at least it spurred me on to think I might be able to do it alone with the DC's. Which I can.
Though I was getting tetchy about the lack of accessible tube stations by the time I got back to Liverpool St.
If I do any more London things, I can't leave my own town until 9.12, getting into London at about 10.24.
So can't meet people before 11am, I think. And that's us getting up at 6.15am!
It's just the cost before 9.12 (what an arbitrary time, too!!), and extra £100 just isn't affordable.
£35 or £137?!
I still can't believe the price difference for travelling in rush hour though. I think that's criminal tbh.
