During the Easter holidays we've booked to spend 24 hrs in London. We will arrive in the afternoon, have a hotel booked for the night, and will stay until late the following afternoon. We'd like to take DS 9 to the Scuence museum first thing in the morning but apart from that don't know what to do. He's been to London once before and that time we went to HMS Belfast, Tate, London Eye, Buckingham Palace.
So I'd love suggestions for what to do when we arrive in London. Wondering about an open top bus tour, so any recommendations please, and then something else to do after the science museum. I really don't know London very well at all so would appreciate any advice or tips. Plus any good suggestions for eating out etc. thanks!
