I want to take DD aged 11 for a day out in London over half term, but I'm stumped for somewhere new to go. We live in Kent an hour away from London by train, so over the years we've done many day trips and a short break. To date we've done-
All the big museums (NHM and SM many times)
London eye
Tate
National gallery
Kew Gardens
Welcome collection
Diana playground
Harrods
Ripleys believe it or not
Museum of London
Sea life centre
She's not really animal mad and I'm not zoo mad so I don't think I want to bother with London zoo, I've vetoed the London dungeons up to now because of her age and I'm still not sure she'd like it (and frankly neither would I) and I doubt she'd know who 95% of the people in Madam Tusards (sp?) are so that's not really worth the entrance fee. She's also a bit over things aimed specifically at primary aged children as they seem mostly too young for her now.
Wise mumsnetters, all suggestions would be gratefully received.
