Hello!
I'm looking recommendations for a day out with a four year old and twin almost two year olds, along with me and my mum. We'll arrive at Waterloo, so somewhere near there would be good, or within reasonable walking distance from there - my mum is a little claustrophobic with the tube, and the ginormous double buggy makes public transport a bit tricky anyway. So far I've thought of the Aquarium. Any other ideas? I'm willing to walk as far as Charing Cross or going towards London Bridge.
Thanks!
