I'm wondering about less touristy or more unusual things to do with DS when we are in London for a couple of days.
We have been several times before & DS has done:
Museums (Natural history, science, Transport, Imperial war, Household Cavalry, National Army)
Galleries (Tate modern, national)
Aquarium
London Eye
Westminster Abbey
St Paul's Cathedral
Cutty Sark
Buckingham Palace, changing of the guard
Open top bus tour + boat on Thames
Selfridges, Harrods, Hamleys
Covent Garden
Greenwich
Olympic Village
Borough Market
China Town
Trafalgar Square
Green Park
Shows: Wizard of Oz, Lion King, Shrek, Matilda
